” But you cannot be Catholic if you live in constant rebellion against the doctrinal authority of the Church. Now I am the one who asks: in what sense can someone who does not believe what the Catholic Church teaches be considered (specifically Roman Catholic)? Is there anyone who can defend the idea that one can be Catholic and not profess the Catholic faith? Saint Paul, inspired by the Holy Spirit, wrote: But even if we or an angel from heaven were to announce to you another gospel other than the one we have announced to you, let it be anathema. We have told you Telegram Number before, and now I say it again: If anyone preaches any gospel to you other than that which you have received, let him be accursed. Gal 1.8-9 And Saint Augustine said: “I would not believe in the Gospel if the authority of the Catholic Church did not move me to it” C. ep. Man. 5,6; cf. C. Faustum 28.2 To Saint Paul I say amen. And to Saint Augustine I say amen. And I don't see a way to be Catholic without saying amen to each other .
Not because he wants to kick anyone out of the Church, but because I understand that it is common sense for it to be so. Paraphrasing the apostle Saint Paul in 1 Cor 13:11-12, when I was a Protestant - atheist, agnostic, etc. - I spoke like a Protestant, I thought like a Protestant, I reasoned like a Protestant . When, by the grace of God, I became Catholic again, I left the things of my Protestant condition as useless. Well, not all, but you understand me. I maintained those that are the common heritage of Catholics and Protestants. Does that mean that I consider as non-Catholic anyone who deviates even one millimeter from the teaching of the Church? Neither . Not believing the same thing as the Church about the Trinity is not the same as rejecting Catholic doctrine on a specific sacramental. Obviously there are degrees in the Catholic doctrinal corpus. And to understand the importance of these degrees, and the consequent canonical consequences, I recommend reading the Apostolic Letter given in the form of 'Motu Proprio' “Ad tuendam fidem” by Blessed John Paul II, Pope. Even so, I warn that if you begin to oppose the teaching of the Church on a “minor” issue, you allow the virus of heterodoxy to enter your soul .
