Why do you insist on continuing to show your lack of education?<quoted text>
Ask your husband to explain this to you...
"The Protoevangelium of James (Gospel of James) talks of Mary being a servant to God. It's not in Scripture, but it's informational."
"It's" = "Mary being a servant to God."
The word "it's" refers to the Gospel of James, which is obvious to anyone who has a reading level above third grade. Notice "it's informational " is the rest of that sentence and clearly shows the word "it's" is referring to the Gospel of James and not "Mary being a servant of God ".
Go ask your wife to teach you something.
