This is an exerpt from a great book by Dale Ahlquist, All Roads: Roamin’ Catholic Apologetics:
Chesterton describes the three stages a convert goes through. The first is deciding to be fair to the Catholic Church. But there is no being fair to it. You are either for it or against it. When you stop being against it, you find yourself being drawn towards it. Then comes the second step, the fun one. It is learning about the Catholic Church, which is like exploring an exotic country full of strange new animals and flowers that you had never imagined existed. It is fun because there is no commitment, and you can run away anytime you want. Which is what the third step is: running away. You do everything you can to avoid becoming Catholic. You know it is the right Church, and you will not admit it, because admitting it means changing your life forever. Your head is convinced, but your heart is still trying to talk you out of it.
One by one, I had dealt with each of my Baptist objections to Catholicism. Any good Baptist is raised with a subtle and sometimes not-so-subtle anti-Catholicism. The Baptist way could almost be described as a point-by-point reaction against and rejection of Catholicism. We rejected the Pope, the priest, the Eucharist, celibacy, saints, confession, crucifixes, and so on. We identified ourselves by the name of a sacrament we also rejected. Though we insisted on “believer’s baptism” and full immersion, we also insisted that it had absolutely no effect on a person whatsoever. It was merely a symbol. The Bible was our final authority in all matters, and we were quite convinced that the Catholic Church deliberately kept its members from reading the Bible in order to keep them ignorant and malleable—which is quite a trick, especially if you can do it for two thousand years.
There is a major hole in the logic of those Christians who protest against the Catholic Church: you cannot use the authority of Scripture to attack the authority of the Church because it was the Authority of the Church that gave Scripture its authority. The hierarchy, the sacraments, the major doctrines of the Catholic Church were all well in place before the Biblical Canon was in place. Centuries in place. And of course it was the Church that authorized the Biblical Canon. Chesterton says he can understand someone looking at a Catholic procession, at the candles and the incense and the priests and the robes and the cross and the scrolls, and saying “It’s all bosh.” But what he cannot understand is anyone saying, “It’s all bosh—except for the scrolls.” The Protestants took the scrolls and walked out of the sanctuary. They left the Church behind. It was a surprise to learn that the Catholic Church, in spite of its reputation among Baptists, is intensely scriptural. Ironically, at any Catholic Mass you will hear far more scripture than at any Baptist service. And it was also my observation that every Protestant sect at some point simply disregards certain Scriptures that are not convenient to its own teachings.
