Got Milk?

The Tragic Irony of "Milk" vs. "Solid Food"

"But I, brothers, could not address you as spiritual people, but as people of the flesh, as infants in Christ. I fed you with milk, not solid food, for you were not yet ready for it. And even now you are not yet ready." (1 Corinthians 3:1-2)

"For though by this time you ought to be teachers, you need someone to teach you again the basic principles of the oracles of God. You need milk, not solid food... But solid food is for the mature, for those who have their faculties trained by constant practice to distinguish good from evil." (Hebrews 5:12, 14)

For 2,000 years, the Catholic Church has been the Mother feeding her children, holding in trust the "solid food" of the faith. This "solid food" is the fullness of divine revelation: the Real Presence in the Eucharist, the authority of Sacred Tradition, the mystery of Apostolic Succession, the deep typology of the covenants, and the profound "word of righteousness" found in the Sacraments.

Yet, for the past 500 years, she has been attacked by many of her own children, who left the home claiming that the "milk" they had was enough, and that the "solid food" was, in fact, poison.

The great and tragic irony, as the verses you cited show, is that the very Scriptures they claim as their sole authority diagnose their condition. The boastful attacks against the Catholic Church are not, as they suppose, a sign of spiritual maturity and scriptural superiority. Instead, they are the very symptoms St. Paul and the author of Hebrews identified as proof of spiritual infancy.

1. The Symptom of Infancy: "Jealousy and Strife" (1 Cor 3)

St. Paul does not leave us guessing how he knows the Corinthians are "infants" and "people of the flesh." He gives a clear diagnosis in the very next verse:

"For you are still of the flesh. For while there is jealousy and strife and divisions among you, are you not of the flesh and behaving only in a human way?" (1 Corinthians 3:3)

The primary evidence of their infancy was division. Their boastfulness was in their factions: "I follow Paul!" or "I follow Apollos!" They were behaving like a human club, not the one, unified Body of Christ.

Does this sound familiar? The very foundation of Protestantism is rooted in this same spirit of division. "I follow Luther!" "I follow Calvin!" "I follow Zwingli!" "I follow my pastor!" This has resulted in tens of thousands of conflicting denominations, each claiming the Bible as its guide, yet all arriving at different conclusions.

When a Protestant attacks the Catholic Church, boastfully claiming his interpretation of the Bible is superior to the 2,000-year-old teaching of the Church Christ founded, he is not acting as a "spiritual person." He is, by St. Paul's own definition, acting as an "infant," engaging in the very "strife and divisions" that prove he is not ready for "solid food." The solid food of Christ is unity (John 17:21), not perpetual schism.

2. The Arrested Development: "You Ought to be Teachers" (Hebrews 5)

The Letter to the Hebrews presents an even more tragic case: spiritual stagnation. The author rebukes his audience because they have been Christians long enough that they "ought to be teachers." Instead, they have regressed. They need to be taught the "basic principles" all over again.

This is the fatal flaw of the sola scriptura (Bible alone) principle. By rejecting the "trained faculties" of the Church—that is, Sacred Tradition and the Magisterium (teaching authority)—it forces every single believer to start from scratch.

• The "solid food" of understanding righteousness, the priesthood, and the sacrifice (the entire theme of Hebrews!) is rejected.
• In its place, they must be "fed again" the "milk" of "faith alone" or "once-saved-always-saved." These are the "basic principles" they can grasp without the "solid food" of Tradition.

The Catholic Church possesses the "faculties trained by constant practice to distinguish good from evil." This is our 2,000-year history of Apostolic Succession, our line of saints and Doctors, our Ecumenical Councils, and the wisdom of the Church Fathers, all guided by the Holy Spirit.

A Protestant who boasts that he and his Bible alone have discovered a "truth" that the entire early Church missed (like the Eucharist being a mere symbol) is not "mature." He is, by the definition in Hebrews, "unskilled in the word of righteousness." He is an infant who has rejected the very teachers God gave him, and therefore must remain on milk, tragically mistaking his simple slogans for the profound "solid food" of God.

3. What Is the "Solid Food" They Reject?

What is this "solid food" that proves so difficult? It is the very heart of the Catholic faith:

• The Eucharist (John 6): This is the ultimate "solid food." When Jesus first preached it, many of His own disciples said, "This is a hard saying; who can accept it?" and they "turned back and no longer walked with him" (John 6:60, 66). The rejection of the Real Presence is the quintessential rejection of "solid food" in favor of a "milquetoast" symbol.
• The Church as Authority (Matt 18:17): "If he refuses to listen even to the church, treat him as you would a Gentile or a tax collector." The solid food is that Christ gave His Church, not a book, the final authority to bind and loose.
• Apostolic Succession (Acts 1:20-26): The understanding that the office of the apostles was meant to be passed on.
• Sacramental Theology: The deep, covenantal understanding of why God uses physical matter (water, oil, bread, wine) to transmit His grace.

 

An Important and Charitable Distinction

It is vital to state that these scriptural critiques do not apply to all Protestants. Many of our separated brothers and sisters are devout, sincere, and humble people who truly love Jesus Christ. They live their faith with a piety that can be a model for Catholics. Many engage in no "strife and divisions" and feel no need to "attack" the Catholic Church, focusing instead on shared Christian virtues and a common love for Our Lord.

The "infancy" described by St. Paul is not a blanket label for everyone outside the visible bounds of the Church. Rather, it is a specific spiritual diagnosis for a specific sickness: the sickness of prideful division.

This critique is aimed squarely at the spirit of anti-Catholicism. The boastful mindset, often seen in professional apologists or certain denominations, that defines itself by attacking the "solid food" of the Church (the Eucharist, the papacy, Sacred Tradition). It is this divisive, "fleshly" behavior that St. Paul identifies as spiritual immaturity, not the simple, humble faith of a Protestant who may be invincibly ignorant of the fullness of the truth. We must, therefore, approach individuals with charity, recognizing the difference between a hostile attacker and a separated sibling in Christ.

Will These "Infants" Be Saved?

This is the most critical question, and it must be answered with both charity and truth. Yes, salvation is possible for them, but it is a path made far more difficult and less certain by their separation from the fullness of the means of grace.

The Catholic Church is clear: we cannot judge the state of any individual soul; that belongs to God alone. However, we have the truth Christ gave us.

1. Baptism is the Key: The Church teaches that a valid Trinitarian baptism (in the name of the Father, Son, and Holy Spirit) incorporates a person into the Body of Christ (Mark 16:16; 1 Corinthians 12:13). Most mainstream Protestants are our validly baptized brothers and sisters. They are "in Christ," even if they are in an imperfect communion with His one true Church. The "infancy" St. Paul speaks of refers to spiritual maturity, not necessarily one's state of grace.

2. The Danger of "Straw" Work: St. Paul, in the very same passage about the "infants" in Corinth, gives a crucial prophecy about judgment. He says that Christ is the only foundation (1 Cor 3:11). But people build on this foundation differently. Some build with "gold, silver, precious stones" (the solid food of the Church's teaching) and others with "wood, hay, straw" (the "milk" of human opinions and divisions).
• "If anyone's work is burned up, he will suffer loss, though he himself will be saved, but only as through fire." (1 Corinthians 3:15)
• This verse directly addresses the salvation of these divisive "infants." It says their work (their denominations, their false doctrines) will be "burned up" at judgment. They may be saved, but only with great difficulty, "as through fire"—a passage the Church has also seen as pointing to the purifying reality of Purgatory.

3. The Role of Ignorance: The Church makes a critical distinction between those who willfully reject the known truth and those who are ignorant of it through no fault of their own (invincible ignorance).
• God "desires all people to be saved and to come to the knowledge of the truth" (1 Timothy 2:4).
• St. Paul, in Romans 2:14-16, explains that God can judge those outside the formal Law by the law "written on their hearts." God judges people based on the grace and truth they were given. A person born and raised in a Protestant community who sincerely loves Jesus and seeks truth is in a very different position than an ex-Catholic who knows the truth of the Eucharist and willfully rejects it.
• For those who do know the Catholic Church is the true Church founded by Christ and still deliberately reject her, their salvation is in grave peril. As Christ said, "If I had not come and spoken to them, they would not have sin; but now they have no excuse for their sin" (John 15:22). 

Final Answer: YES! By the grace of Christ, our separated brothers and sisters can be saved. Their valid baptism is the doorway. However, by living on "milk," they are spiritually malnourished. By rejecting the "solid food" of the Eucharist, they are depriving themselves of the "bread of life" (John 6:35). And by remaining in "strife and divisions," their work is built of "straw" that will be burned away.

Our duty is not to condemn them, but to pray for them and charitably show them the "solid food" they are missing, so they may come into full communion and walk the surest and fullest path to salvation that Christ established: the Holy Catholic Church.
