If agrees with the Holy Scripture by providing missing biographical detail. It doesn’t mean the Protoevangelium is wholly inspired or accurate.
It does not agree with Scripture because it teaches things which are contradicted BY Scripture.
It doesnt mean the Protoevangelium is wholly inspired or accurate.
If there's no certainty of inspiration or accuracy, then one is left picking and choosing which parts they WANT to believe and don't know if they're believing the parts which are fables or not. In that case, anyone who believes it is a fool.
Listen to this statement of what you termed “poetic liberty” in the Evangelium:
“But Mary had forgotten the mysteries of which the archangel Gabriel had spoken, and gazed up into heaven, and said: Who am I, O Lord, that all the generations of the earth should bless me? And she remained three months with Elizabeth; and day by day she grew bigger. And Mary being afraid, went away to her own house, and hid herself from the sons of Israel. And she was sixteen years old when these mysteries happened.”
An angel from God visits and announces one of most momentous events in human history to Mary and....oops! she forgot! AND SHE FORGOT! FORGOT AN ANGEL'S VISIT AND HIS MESSAGE!
Shall I go dismantling this fraud? It's like a one legged table, stand back from it and it will fall over on its own.
