[Where we got the Bible: Our Debt to the Catholic Church.](http://www.catholicapologetics.info/apologetics/protestantism/wbible.htm) You have to understand that Catholics don't believe in *Sola Scriptura* because it's completely false. The Church codified the canon of scripture; ergo, she alone has the authority to interpret it, not protestants. Besides, even scripture condemns the idea of *Sola Scriptura* by history for one, and St. Paul himself: 2 Thess 2:14 "Therefore, brethren, stand fast; and hold the traditions which you have learned, whether **by word**, or by our epistle." Scripture and tradition, that is what we believe, that is what has always been taught for 2000 years, until the protestant heretics came. So, it is ludicrous to believe that every doctrine is required by scripture since scripture is only one part of divine revelation, not the whole. However, there is no Catholic doctrine contradicted by scripture, it's simply impossible because that would make God a liar. Ok, on to your "objections". - Excommunication Matthew 16:18-19 "And I say to thee: That thou art Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it. [19] And I will give to thee the keys of the kingdom of heaven. **And whatsoever thou shalt bind upon earth, it shall be bound also in heaven**: and whatsoever thou shalt loose upon earth, it shall be loosed also in heaven. Luke 10:16 "He that heareth you, heareth me; and he that despiseth you, despiseth me; and he that despiseth me, despiseth him that sent me." Speaking to the apostles. If any man cuts himself off from the Church by heresy or some other detestable act, the Church has every right to excommunicate him, so that he will seek repentance and return to the fold, I'm not sure why this is a hard concept to understand. ------ Indulgences You can read about them [here](https://www.fisheaters.com/indulgences.html) and in many other places. [This article explains it in great detail as well.](https://sspx.org/en/news-events/news/indulgences-churchs-treasury-merits-2420) ------ Sabbath Jesus Christ rose from the dead on a Sunday. Also, we're not Jews. The Church has done this practice from the beginning, I'm surprised it's even a question. Christ revoked the old covenant and established a new one. The new sabbath is Sunday because Christ conquered death on Sunday and secured our redemption. And Acts 20:7. ----- The revised 10 Commandments The prots moved them around, not us. https://www.fisheaters.com/10commandments.html ----- The practice of praying to angels and saints. https://www.scripturecatholic.com/saints-and-intercessory-prayer/ ----- The notion they have the authority to ordain saints. Again, I'll point you back to Matthew 16:18-19. Canonization requires a number of miracles to be performed by the saint after their death and their life determined to be one of heroic virtue. You can read plenty about this. Prior to Vatican II, at least 2 miracles were required as well as the "devil's advocate" panel during the canonization process. There is debate as to whether canonizations themselves are infallible, most theologians agree prior to Vatican II they were, but again it's still debated. Either way, I think 99.9999999% of Catholics would agree that canonizations prior to Vatican II are legitimate and trustworthy. ------ The rosary Do you pray the Our Father? The Rosary is entirely scriptural. Christ was referring to pagans when he was talking about vain repetitions. Also, it's prideful to assume that all Catholics are vaingloriously repeating prayers to be seen. I would encourage you to read [The Secret of the Rosary by St. Louis De Montfort](https://www.virgosacrata.com/catholic/the-secret-of-the-rosary) and this: https://aleteia.org/2016/10/20/yes-the-rosary-is-a-completely-biblical-prayer/ ----- Vicarius Filli Dei This is pretty easy to answer. It English is translates to "Vicar of Christ". Meaning, Christ's representative on earth. This is consistent with Matthew 16:18-19 again. The pope has the power to bind and loose, Christ gave him this power and the keys to do it, ergo, He is Christ's vicar on earth, since Christ is reigning in Heaven and not physically present ruling over the Church on earth, except in the Eucharist. I hope that answers your questions. I will pray for your conversion to the one, true, holy, Catholic, and apostolic faith outside of which no one is saved.
