“Once you’re convinced Catholicism is true, is converting really necessary? That question might sound strange to some readers. After all, if you believe that the Catholic Church really is the Church founded by Christ, why wouldn’t you convert?
Well, lots of reasons. Maybe you’re part of a solid Protestant community. Maybe converting would create serious tension in your marriage or with your parents. Maybe you would lose your job in ministry. In some of the most extreme cases, maybe you live in a country in which converting to Catholicism is a capital crime. In short, people weighing whether to become Catholic are often dealing with much more than simply answering the question, “Is it true?”
But as serious and well-grounded as those hesitations may be, the Second Vatican Council doesn’t mince words:
In explicit terms [Jesus] himself affirmed the necessity of faith and baptism and thereby affirmed also the necessity of the Church, for through baptism as through a door men enter the Church. Whosoever, therefore, knowing that the Catholic Church was made necessary by Christ, would refuse to enter or to remain in it, could not be saved. (CCC 846)
This is simply a restatement of what Catholics have been saying for two millennia. The Church is, in St. Paul’s words, Jesus’ “body, the fullness of Him Who fills all in all” (Eph. 1:23). To try to have Jesus without the Church is to try to have Christ the head without the body of Christ, or to put asunder what God has joined together (Matt. 19:6; Eph. 5:30-31). In short, as the Catechism puts it (795), it’s not a matter of choosing among denominations, but about accepting the “whole Christ” (Christus totus), head and body.
Significantly, we’re not talking about a person who is innocently unaware of the Catholic Church or is still trying to sort out the truth of the Catholic claim. The person who sees the truth of the Catholic claim and yet refuses to respond to it is knowingly rejecting the fullness of Christ, cutting themselves off from salvation.
If that seems like a steep cost, it should. Jesus was explicit that His message might prove destabilizing for family peace (Matt. 10:34-38):
Do not think that I have come to bring peace on earth; I have not come to bring peace, but a sword. For I have come to set a man against his father, and a daughter against her mother, and a daughter-in-law against her mother-in-law; and a man’s foes will be those of his own household. He who loves father or mother more than me is not worthy of me; and he who loves son or daughter more than me is not worthy of me; and he who does not take his cross and follow me is not worthy of me.
Or more pithily: “if any one comes to Me and does not hate his own father and mother and wife and children and brothers and sisters, yes, and even his own life, he cannot be my disciple” (Luke 14:16). Jesus compares the decision to follow Him to that of a king deciding to go to war against an invading army twice his size (vv. 31-33). In other words, it’s not the kind of decision one ought to make lightly. It’s going to cost something.
You might object here: “I’m not saying not to follow Jesus—I’m just saying not to become Catholic!” But the whole point is that for the person for whom Jesus has revealed the truth of the Catholic Church, remaining Protestant (or Orthodox, etc.) is to cease to follow Him. It does no good to say we’re going to follow Jesus on our terms, just as it would have done Jesus’ original listeners no good to say they were going to follow the God of Abraham on their own terms. If Jesus shows you the way in which He wants you to follow him, that’s not the time to do your own thing or stay in your comfort zone. That’s the time to pick up your cross and follow Him, even if He’s leading you somewhere weird and uncomfortable (like the Catholic Church). (Quo vadis, Domine?)
Fortunately, though, Jesus doesn’t just tell us about the high cost of discipleship. He also promises us that these earthly costs of converting will be worth it. He tells the rich young man, “Go, sell what you possess and give to the poor, and you will have treasure in heaven; and come, follow me” (Matt. 19:21). Perhaps piqued by this mention of heavenly treasure, St. Peter then asks, “Lo, we have left everything and followed you. What then shall we have?” (v. 27). Jesus responds by promising that “every one who has left houses or brothers or sisters or father or mother or children or lands, for My name’s sake, will receive a hundredfold, and inherit eternal life” (v. 29).
In other words, discipleship isn’t just about sacrifice, but about investing, laying up for ourselves “treasures in heaven, where neither moth nor rust consumes and where thieves do not break in and steal” (Matt. 6:20). Converting to Catholicism can be scary, and it can be costly. But take courage: whatever it costs you will be well worth it, both in this life and in the life to come.”

Chesterton, “When we pray we speak to God; but when we read, God speaks to us.” -St Jerome, "As the reading of bad books fills the mind with worldly and poisonous sentiments; so, on the other hand, the reading of pious works fills the soul with holy thoughts and good desires." -St. Alphonsus Liguori, "And above all, be on your guard not to want to get anything done by force, because God has given free will to everyone and wants to force no one, but only proposes, invites and counsels." –St. Angela Merici, “Yet such are the pity and compassion of this Lord of ours, so desirous is He that we should seek Him and enjoy His company, that in one way or another He never ceases calling us to Him . . . God here speaks to souls through words uttered by pious people, by sermons or good books, and in many other such ways.” —St. Teresa of Avila, "I want a laity, not arrogant, not rash in speech, not disputatious, but men and women who know their religion, who enter into it, who know just where they stand, who know what they hold and what they do not, and who know their creed so well that they can give an account of it, who know so much of history that they can defend it. I want an intelligent, well-instructed laity… I wish you to enlarge your knowledge, to cultivate your reason, to get an insight into the relation of truth to truth, to learn to view things as they are, to understand how faith and reason stand to each other, what are the bases and principles of Catholicism, and where lie the main inconsistences and absurdities of the Protestant theory.” (St. John Henry Newman, “Duties of Catholics Towards the Protestant View,” Lectures on the Present Position of Catholics in England), "We cannot always have access to a spiritual Father for counsel in our actions and in our doubts, but reading will abundantly supply his place by giving us directions to escape the illusions of the devil and of our own self-love, and at the same time to submit to the divine will.” —St. Alphonsus Ligouri, "The harm that comes to souls from the lack of reading holy books makes me shudder . . . What power spiritual reading has to lead to a change of course, and to make even worldly people enter into the way of perfection." –St. Padre Pio, "Screens may grab our attention, but books change our lives!" – Word on Fire, "Reading has made many saints!" -St Josemaría Escrivá, "Do you pray?

And this I believe is heard.” -GM Hopkins, SJ, "Only God knows the good that can come about by reading one good Catholic book." — St. John Bosco, "Why don't you try explaining it to them?" – cf St Peter Canisius, SJ, Doctor of the Church, Doctor of the Catechism, "Already I was coming to appreciate that often apologetics consists of offering theological eye glasses of varying prescriptions to an inquirer. Only one prescription will give him clear sight; all the others will give him at best indistinct sight. What you want him to see—some particular truth of the Faith—will remain fuzzy to him until you come across theological eye glasses that precisely compensate for his particular defect of vision." -Karl Keating, "The more perfectly we know God, the more perfectly we love Him." -St Thomas Aquinas, OP, ST, I-II,67,6 ad 3, “But always when I was without a book, my soul would at once become disturbed, and my thoughts wandered." —St. Teresa of Avila, "Let those who think I have said too little and those who think I have said too much, forgive me; and let those who think I have said just enough thank God with me." –St. Augustine, "Without good books and spiritual reading, it will be morally impossible to save our souls." —St. Alphonsus Liguori "Never read books you aren't sure about. . . even supposing that these bad books are very well written from a literary point of view. Let me ask you this: Would you drink something you knew was poisoned just because it was offered to you in a golden cup?" -St. John Bosco " To teach in order to lead others to faith is the task of every preacher and of each believer." —St. Thomas Aquinas, OP. "Prayer purifies us, reading instructs us. Both are good when both are possible. Otherwise, prayer is better than reading." –St. Isidore of Seville “The aid of spiritual books is for you a necessity.… You, who are in the midst of battle, must protect yourself with the buckler of holy thoughts drawn from good books.” -St. John Chrysostom
