Which parts? I don't see any such claims, and Luke and Paul (whoever they were) explicitly tell us that they were not on the scene of the crime, so to speak. In a way I agree with you though as I see very close to zero history and eye witness testimony in the Bible.
Gospel of John for example... Also, the Exodus is in tradition written by Moses, and the mystery writer of this book has a very accurate knowledge of the geography of that area.
Ok, the historical parts of the Bible are based on eye witness accounts. either the writer saw the happenings, or wrote down what an eyewitness told him.
Regardless, you haven't separated your religion/church's belief from other similar religions'/churches' beliefs. Do you know what I mean? The Koran, Torah, and most other religious writings have similar evidence to that which you describe above. What makes your religion/church's belief MORE believable than other religions and churches?
Quite simply because all other religions lack or err in something which God obviously wouldnt put in His religion.
Please show me a religion which is united as one. Like everybody believes the same core beliefs in that religion. Its not an "interpret what you want" thingy.
Thats holy.. meaning the teachings of the religions are objectively holy. reading the catechism would be a good place to examine this.

thats universal... a Church thats for everybody of every race and age and gender. essentially worldwide, not excluding anyone.
actually, we should first determine whether God exists or not, and define God, then the next step would be to figure out what religion He founded.
ok, so Patrick, whats the cause of your existence?
EDIT: I know lots of people believe that life began from apes, and all that stuff, but Im wondering, because of the second law of thermodynamics, which states that the universe continues to grow in randomness.. how did something so unrandom as life ever come to exist? I just thought of this and it doesnt seem to make sense to me.... :S cuz Im not saying that evolution etc. etc. isnt true, Im just trying to figure out how all these things happened which have such a small probability and seem to go against the second law of thermodynamics.
