Since the great majority of the over 41,000 ‘Christian’ denominations declare the resurrection of Jesus Christ, I will risk 'resurrecting' this dormant thread.
One of the great reasons there are so many gospels(or denominations as many people call them) is that very few people are willing to put up with God as He reveals Himself in the Bible, so they form Him to suit their desires. This involves adding to, subtracting from, changing, or just misunderstanding, the scriptures.
It is interesting that ‘faith vs superstition’ is under discussion here, because the reason I first ‘made a ripple’ here was to post a link on a thread about Acts 17 To the unknown God. Coincidentally(yeah right), Paul begins his discourse to the Athenians with superstition(v. 22), and ends with faith(v. 31). Superstition is how man makes the gods he wants, and faith is what God gives a man to allow or cause him to believe in the resurrection.
The Bible also says(Rom. 10:17) that faith comes by hearing, and hearing by the Word of God. A person may hear enough to have faith, but deviations in doctrines after the basic faith in the resurrection of Jesus Christ are abundant, mostly because few people are happy with God as He describes Himself, so they change Him into something else. There are also obviously some who spend time, perhaps a lifetime, in church(es) without ever being sure of the resurrection, because that's what those around them are doing.
The really good news(which is rarely preached or believed) is that Jesus Christ has been tasked with reconciling all of creation unto himself, and thereby to God. He always does the Father’s will, so we can rest assured he will not leave us hanging.
In the grand scheme of things therefore, no matter what ‘flavor’ of Christianity we end up with(or without), God’s loving arms are long enough and strong enough to catch us and hold us close.
