Greetings to my Catholic brothers in Christ. I grew up in a more evangelical type background that viewed Catholicism as legalistic and works-focused. As I've matured and studied my faith more I've come to have great respect for the Catholic church for its philosophical and scientific heritage. However, I still have a few questions that I was hoping a few informed Catholics might actually be able to shed some light onto. Thanks!
1) How can we claim that Peter represents unbroken apostolic succession back to Christ when James the brother of our Lord was the head of the Church of Jerusalem? (Indicated in some of Paul's writings and mentioned by contemporary historians) I don't have an issue with the head of the church per se, but I don't know how to reconcile man's fallibility with the idea that there's a man who make papally infallible assertions.
2) What's the backing for transubstantiation? I don't see anything in scripture besides Jesus saying "This is my body/blood," but given how many things in the Bible and even Jesus' teachings are allegorical why is it necessary to take this literally?
3) Does Catholicism put church teaching and tradition on the same level as scripture? This ties back to the first one, of all the Protestant theology I've studied I gravitate most toward sola scriptura.
4) Why do I need to pray to saints rather than directly to God? If, as the writer of Hebrews says, we can approach the throne of God with boldness and confidence, why shouldn't I do that in favor of going through another person?
Thanks for any help you can give me there lads.
