I would bring up the point that the Bible itself answers the question.... The fact she and Joseph were angry at the young Jesus forbeing in the temple for days without them knowing it, shows Mary was not perfect and sinless ...(1) If, in fact, we look to the Bible for answers, "angry" is not in the Bible. 'Being angry' is an extra-scriptural interpretation of this passage. I'll grant you 'astonished' and 'anxious' (NIV), but not angry.
(2) For argument's sake, even if 'angry,' what makes anger per se a sin? Was not Jesus 'angry' -- in the extra-biblical sense, of course -- when he 'cleansed the temple'? If so, can only divine persons be 'angry'?
... she would have known exactly where he was because she would have been sinless and perfect and understood this being that way
3) I'm curious about equating sinlessness and omniscience. Is ignorance sinful?
God bless.
Perhaps ‘angry’ isn’t the term used but it is clear they were unhappy with Jesus. They did admonish him because they did not know where he was. If you consider this to be a typical parental reaction to a teen-aged child disappearing on his parents, who were heading out of town from the temple, and had to come back and search for him to find him. They were searching for him for 3 days!
Luke 2:41-50. 48 “And when they (Mary and Joseph) found Him, they were astonished, and His mother said to Him, “Son why have You treated us this way? Behold your father and I have been anxiously looking for you.”
49 And He said to them, “Why is it that you were looking for me? Did you not know that I had to be in My Father’s house?”
50 And they did not understand the statement which He had made to them.
Mary claims Jesus has not treated them well by disappearing on them, and causing her and Joseph to worry about him and anxiously searching for Jesus for 3 days. Sinless people do not bring false charges against another person, much less the perfect and sinless Son of God. Doing that would also show they had not lived a perfect life.
They also failed to recognize Jesus’ reference to the temple being His heavenly Father’s house and that it was the logical place for Him to be.
Fact is Jesus was telling his earthly parents they should have known where he was and not have acted the way they did, and the next verse explains they did not understand his explanation as to why they should not have acted that way. It wasn’t righteous anger like God’s pure and perfect righteous anger because God reacts to the fact and truth of what people do, not incorrectly like regular people do.
My other larger point, that the Bible in multiple places states ALL people are sinful and need a savior, Mary herself saying so, shows beyond rebuttal that Mary was sinful and did not lead a perfect life. Some in the church over time have elevated her attributes far above the biblically historical Mary is.
