The problem is it’s got a lot of convenient contradictory statements in it.
For example:
He said to them, “But now, the one who has a purse must take it, and likewise a bag. And the one who has no sword must sell his cloak and buy one.
Luke 22:36
This part isn’t in Marcion’s version of Luke, which is probably the earliest extant version. But it is in the canonical version.
Something very convenient given it reversed the ban found across the Synoptics on carrying a purse when ministering, which necessarily prevented taking people’s money.
Just a bonus that it also allowed for the church to take up swords too right around before the time they start executing people for ‘heresy.’
There’s plenty of problematic passages added in over the years:
Just then a Canaanite woman from that region came out and started shouting, “Have mercy on me, Lord, Son of David; my daughter is tormented by a demon.” But he did not answer her at all. And his disciples came and urged him, saying, “Send her away, for she keeps shouting after us.” He answered, “I was sent only to the lost sheep of the house of Israel.” But she came and knelt before him, saying, “Lord, help me.” He answered, “It is not fair to take the children’s food and throw it to the dogs.”
