I would congratulate the Protestants on happy "Reformation Day" - but I'm not sure which one of the hundreds of heretical sects (who anathematize each other) I should choose.
Instead, I'll lament the devil's success and ask for the intercession of St. Joseph and Holy Theotokos!
The objection begins from a premise. Sexual union is biological, and biology requires no moral weight. On that reading, loading the act with moral significance adds gravity to something animal. The Church's careful teaching then reads as unease toward the body.
CCC 2361 rejects the premise at its root. Sexuality, by means of which man and woman give themselves to one another through acts proper and exclusive to spouses, is not something simply biological. It concerns the innermost being of the human person as such.
The paragraph also fixes where the act becomes fully human. Sexuality is realized in a truly human way only within love that commits a man and woman totally to one another. The excerpt states the measure of that commitment, which lasts until death (CCC 2361).
What CCC 2362 says of the acts answers the remaining suspicion. In marriage they are noble and honorable. Their truly human performance fosters the self-giving they signify and enriches the spouses in joy and gratitude. Sexuality is even named a source of joy and pleasure.
The premise fails on the excerpts' own terms. What the objection counts as merely animal, the Catechism describes as touching the innermost being of the person, noble and honorable, and a source of joy. The moral weight belongs to the act because the act belongs to a total giving of self until death.
He was revealed to take away sins. That clause sits inside the Catechism's explanation of why the Word became flesh. It names the purpose of the Incarnation as an action performed rather than a status conferred (CCC 457).
The same paragraph states the reason plainly. The Word became flesh for us in order to save us by reconciling us with God. Reconciliation is then anchored in Scripture, where God loved us and sent his Son to be the expiation for our sins.
The witnesses continue in the same direction. The Father has sent his Son as the Saviour of the world, and he was revealed to take away sins. Every phrase binds the Son's coming to a work done for sinners, carried out because the Father loved and sent.
This stands behind the Creed's confession. For us men and for our salvation he came down from heaven (CCC 456). By the power of the Holy Spirit he became incarnate of the Virgin Mary, and was made man.
Read together, the two paragraphs give the coming both its manner and its aim. The Creed confesses how he came. The Catechism's clause supplies the aim, which is the taking away of sins through the Son whom the Father sent in love.
"Prayer changes things" is the popular slogan. Aquinas would correct you: prayer changes nothing in God, and everything in the plan.
Most people assume that if God is unchanging, petitionary prayer is incoherent. You are asking an eternal mind to change its mind. Either prayer works and God is mutable, or God is immutable and prayer is theater.
Aquinas rejects the dilemma entirely.
In the Summa Theologiae (II-II, q. 83), he argues that God's will is eternally fixed. No request alters it. But that is not a problem for prayer. It is the very reason prayer exists.
Providence does not merely decree ends. It ordains the means. And God has willed to give certain goods through the instrument of your petition. Not because He needs your input, but because He chose to accomplish His plan through secondary causes.
The farmer's irrigation is the ordained means of the harvest. He does not beg rain into existence against the order of nature. He cooperates with it.
So when you petition God, you are not informing Him of your needs. He knew them before you did. You are, in Aquinas's terms, meriting the reception of what He eternally intended to give through that very act of asking.
Prayer is also an act of the virtue of religion. It orders the soul toward God as the source of every good. The petition changes you before it changes anything else.
This is why " Thy will be done" is not resignation. It is the most precise description of what prayer actually does.
The modern assumption is that a fixed plan makes prayer pointless. Aquinas answers: a fixed plan is what makes prayer powerful.
Does this resolve the tension for you, or does petitionary prayer still feel like it requires God to genuinely reconsider?
Modern scholarship claims early worship was an open, simple memorial service. But Cyril of Jerusalem's 4th-century Mystagogical Catecheses show something else entirely: a Church of sealed rites, guarded mysteries, and sacraments that do things.
Notice the logic. If the rites were mere symbols, the early Church's practice of secrecy makes no sense. You do not hide a metaphor. You explain it openly, because a picture needs interpretation.
But Cyril's Church guarded these rites the way you guard something that acts. Because on their account, the anointing objectively marks the soul, and eating the consecrated elements is encounter, not recollection.
Memorialism cannot explain the discipline of the secret. Sacramental realism explains it perfectly.
The assumption that early worship was a non-sacramental memorial service is not ancient. It is a modern reconstruction, and documents like Cyril's quietly dismantle it. In the 4th century, in Jerusalem, steps from where Christ died, new Christians were being told they had been sealed and anointed into Christ Himself.
Which claim fits the evidence better: sacraments as symbols, or sacraments as realities?
Repost the first post if this sharpened the historical picture for you.
"Christianity is a relationship, not a religion." Aquinas would say that sentence is a category error, not a slogan.
In the Summa Theologiae (II-II, q. 81), Thomas treats religion (religio) as a moral virtue under Justice. Not a feeling. Not a preference. A virtue.
And justice, classically defined, means rendering to each what is due.
Here is the move most people miss. God is the source of your existence at every moment. You receive being, motion, and every good you have from Him. That creates a real debt. Not a metaphorical debt. An objective obligation of justice.
And because the gift is infinite, the debt of worship is infinite in kind. You literally cannot over-pay it. Adoration, sacrifice, thanksgiving, devotion. These are not "religious overhead" obscuring a relationship. They are the acts by which the debt is acknowledged.
Thomas even defends external acts of religion, devotion, prayer, sacrifice, adoration, precisely against the idea that worship is merely internal. A purely private, invisible religion is a truncated religion. The virtue demands outward expression, because justice between persons is never purely invisible.
Notice the irony. The slogan says "relationship, not religion." But what relationship survives on no obligations, no acts of honor, no rendered due? We call that neglect, not intimacy.
Aquinas would say the relationship is real. But it is carried by religion, not replaced by it.
So the honest question: when you say "not a religion," do you mean freedom from empty ritual, or freedom from owed worship?
The Catechism teaches that defending human reason's ability to know God expresses confidence in speaking about him to all men and with all men. That confidence extends to dialogue with other religions, with philosophy and science, as well as with unbelievers and atheists. The same teaching sets a boundary: since our knowledge of God is limited, our language about him is equally so. We can name God only by taking creatures as our starting point, in accordance with our limited human ways of knowing and thinking.
Put those two clauses together and one practical judgment follows. Since every name we give God begins with creatures, a conversation with an atheist can reasonably begin there rather than wait for shared doctrine. Start from something created that both speakers can already see and name. Then let the limits of your language discipline the claims you make instead of treating them as a reason to stay silent. The excerpts establish that such speech is possible and where it must begin; they do not promise that any dialogue will succeed.
Two claims about Scripture stand side by side in the Catechism, and they are easy to run together. One concerns what Scripture is. The other concerns why it can be trusted.
The first claim answers the question of identity. Hugh of St. Victor teaches that all Sacred Scripture is one book, and that this one book is Christ. His reason runs along the same line: divine Scripture speaks of Christ, and divine Scripture is fulfilled in him (CCC 134).
The second claim concerns authority rather than identity. God is the author of Sacred Scripture because he inspired its human authors, acting in them and by means of them (CCC 136). Because he is its author, he gives assurance that their writings teach without error his saving truth.
Keeping the two apart shapes how anyone actually reads. Unity is a claim about subject matter: ask of any passage what it says of Christ, and the library reads as one book. Trustworthiness is a claim about authorship: human writers wrote, yet God who acted through them guarantees the saving truth they teach. The Catechism states both, and neither takes the place of the other.
Modern Christianity treats communion as a symbol believers perform. The early Church treated it as medicine the dying needed to receive.
The practice was called Viaticum, literally "provisions for the journey." When a Christian was near death, the Church did not merely pray beside the bed. The Eucharist was brought and given as food for the passage from this life to the next.
This only makes sense if the Eucharist is what the Church claimed it was. A symbol cannot strengthen a soul facing judgment. A memory cannot accompany anyone anywhere.
Ignatius of Antioch, writing in the early second century, called the Eucharist the "medicine of immortality" and the antidote that prevents death and gives life in Christ. He did not mean this poetically. He meant that consuming the consecrated bread objectively unites the believer to the risen Christ, whose body destroys death.
The logic is inescapable. If communion is a memorial meal, then giving it to the dying is sentiment. If it is the true Body of Christ, then refusing it to the dying would be cruelty, like withholding food from a starving traveler.
Catholics still do this today. The priest brings the Host to the bedside, and the person receives the same Christ that Ignatius said the early faithful received.
The sacraments are not pictures of grace. They are grace arriving.
Which is it in your tradition, and does your practice at the deathbed match your answer?
Most modern Christians treat Communion as a symbolic memorial. Bread and juice, a mental remembrance, nothing more.
But around 180 AD, a bishop named Irenaeus of Lyons taught something radically different. The Eucharist physically becomes Christ's body, and eating it prepares your body for resurrection.
A thread.
"Our bodies, being nourished by it, and deposited in the earth and suffering decomposition there, shall rise at their appointed time, the Word of God bestowing on them the resurrection to the glory of God." (Against Heresies 5.2.3)
The point is physical. Not a metaphor. Not a spiritual reminder. Real food for a real body, destined for a real resurrection.
The earliest surviving theological argument for the Eucharist is not about symbolism at all. It is about Christ's real body nourishing yours for glory.
The memorialist view has to explain why a man taught by Polycarp, taught by John, knew nothing of it.
If you found this valuable, repost the first tweet. And tell me: does this change how you read John 6?
Modern assurance of salvation is often just a rebranded version of the medieval sin of presumption.
That is not an insult. It is a precise scholastic diagnosis.
Thomas Aquinas treated presumption as a vice directly opposed to hope. His definition: confidence in God's mercy that ignores the necessity of cooperating with grace on your part. You assume the outcome is locked in, so the striving becomes optional.
Notice what that does. It does not love God's mercy. It uses it.
Aquinas goes further. He argues that the virtue of hope cannot exist without the fear of the Lord. Not servile terror, but filial fear: the sober awareness that you can walk away from grace, and that mortal sin genuinely kills the life of God in the soul.
Remove that fear, and hope collapses into its counterfeit. Assurance without the possibility of loss is not hope at all. It is presumption wearing hope's clothes.
The pattern repeats: confidence in mercy, contempt for cooperation, neglect of works, and a "peace" that Scripture never offers. Paul warned exactly this. "Let him who thinks he stands take heed lest he fall."
The medieval doctors saw this coming a mile away, because they had already catalogued it.
The question worth wrestling with: if your assurance survives even deliberate unrepented sin, is that faith in Christ, or faith in a doctrine about yourself?
The puzzle sits inside a single sentence of the Catechism: true development concerns the whole man, increasing each person's ability to respond to his vocation and to God's call. If development were only output, that sentence would be decoration. It instead names a capacity, the ability to answer.
A second passage stands beside it with questions of its own. How can we not recognize Lazarus, the hungry beggar of the parable, in the multitude of human beings without bread, a roof, or a place to stay? And how can we fail to hear Jesus say that what we did not do for one of the least of these, we did not do for him?
Neither excerpt explains how any community would measure such ability or what steps would follow from it. Paragraph 2461 fixes the aim of development in the whole man and his capacity to answer. Paragraph 2463 asks us to recognize that same man among those without bread, a roof, or a place to stay. The two run side by side; neither becomes the other, and neither settles what the other leaves open.
The recognition question carries its own weight. As Matthew 25:45 records it, what you did not do for one of the least of these, you did not do for him. Development that never reaches that verse has not yet answered the question the Catechism sets before it.
