Making Converts of Cradle Catholics
Practical Protestantism
A practical atheist claims to believe in God but lives like an unbeliever; a practical Protestant professes to be Catholic but practices his religion like a Protestant.
Remember that the essence of being converted to Catholicism is recognizing the teaching voice of the Church as the teaching voice of Christ. Everything else will follow. But suppose we do not? Whose voice do we substitute for the voice of the Church? Who speaks for Christ?
Protestants claim it is “Scripture alone,” but this assertion does not get to the heart of the matter. To derive Scripture’s meaning, one must interpret it. And each individual
must decide for himself which interpretation to accept. In the end, Protestantism comes down to a private judgment: what
I think the Bible says. Ultimately, there is no authoritative voice that one can be sure echoes the voice of Christ.
** When a Catholic fails to accept the authority of the Church to teach in the name of Christ, he has in effect adopted the underlying rule of Protestantism as his divining rod: his own personal judgment. Rather than humbly accepting the truth—that deposit of faith entrusted to the Church—he makes himself the judge over truth: “I’ll accept this, but I won’t accept that.”**
How can we know if practical Protestantism is blocking someone’s conversion to belief in the Church? He may say, “I don’t see anything wrong with artificial contraception.” Or, “I don’t understand why the Church says it’s a sin to miss Mass on Sunday. What’s the big deal?” Or, “I don’t think the documents of Vatican II are valid.”
** He is actually saying: “If I don’t see it, understand it, agree with it—if it does not correspond with my personal views—then I don’t have to accept or obey the Church’s teaching.”**
You’ll notice that this affliction of practical Protestantism can swing either left or right. It makes itself evident whenever we think we know better than the Church. If we reject the teachings of an ecumenical council, if we refuse “religious submission of mind and will” (LG 25) to the Church’s magisterium—even its ordinary magisterium—or if we insist on remaining “loyal” to an alleged apparition after the Church has ruled that it is not worthy of belief, we have stepped outside the realm of Catholicism into practical Protestantism. For we are not merely rejecting a particular teaching of the Church; we are denying the Church’s divine prerogative to teach and govern authoritatively—that is, with the authority of Christ.
Even if we claim to be “more Catholic than the pope,” we have revealed that we have yet to be converted to a real understanding of what the Church is and what it means to be Catholic. We are forgetting that “the Church”—and not our idea of what Catholicism ought to be—is “the pillar and bulwark of the truth” (1 Tim. 3:15).
Highlighting this conflict between practical Protestantism and authentic Catholicism points out the need for Catholics to experience a deeper conversion to the Church. And this need must be acknowledged, because an individual will not seek to become Catholic at heart if he thinks he already is.
So what are the dispositions of heart and life-changing truths that helped bring so many into the Church and that, if fostered, may turn cradle Catholics into converts?
