It agrees with the scripture though. It disagrees with the false ideas about the scripture prevalent among the Protestants. See, for example, the common misunderstanding that Romans 3 (or the Psalm from which that passage is a citation) teaches of sinfulness of Mary.
And your statement is false logic. All historical literature reflects some bias, but it is evidence of facts nevertheless. It should be read critically, but it cannot be dismissed altogether either because it has inaccuracies, or because it is not inspired scripture.
Does it? Mary had a son named Jesus, she and Joseph married.
Is that the degree to which it agrees with Scripture? I've already pointed out how the Evangelium contradicts Scripture but if I error you have not said in what way, saying, “it agrees with scripture though” doesn't present any real argument.
If Protestants or I misunderstand Romans 3 and Paul's statements about all persons sinning, what is the misunderstanding and what is the error?
“All historical literature reflects some bias, but it is evidence of facts nevertheless”
So the Evangelium is evidence of what facts? What is the support for the things is asserts?
Are there better, more reliable sources available that agree or contradict?
“It should be read critically, but it cannot be dismissed altogether either because it has inaccuracies, or because it is not inspired scripture.”
Fair enough...You posted the Evangelium in whole, what parts would you dismiss as inaccurate, false, etc.? If any?
So take your editorial blue pencil and give me just those parts you see as accurate or on the other hand those parts you would pencil out as inaccurate and bias.
I don't dismiss the Evangelium because it is not Scripture any more than I would Josephus but rather because it contradicts Scripture which I regard as inspired by God. I regard it much like you might regard that movie with Tom Hanks in it about Templar Knights and stories of Jesus having children.
