This is off topic. Why do you ask?
Actually, it’s not off topic. There are many Protestant denominations that celebrate Christmas, have pictures of Jesus or crosses mounted inside or outside their Churches. Your condemnation, according to your interpretation, crosses more lines than just Catholic.
I ask about the authority of who explained your interpretation to you, because scriptures teach us the people of the Old Testament had to have an ‘authority’ to explain scriptures to them.
**Nehemiah 8
1And all the people gathered themselves together as one man into the street that was before the water gate; and they spake unto Ezra the scribe to bring the book of the law of Moses, which the LORD had commanded to Israel.
2And Ezra the priest brought the law before the congregation both of men and women, and all that could hear with understanding, upon the first day of the seventh month.
3And he read therein before the street that was before the water gate from the morning until midday, before the men and the women, and those that could understand; and the ears of all the people were attentive unto the book of the law.
4And Ezra the scribe stood upon a pulpit of wood, which they had made for the purpose; and beside him stood Mattithiah, and Shema, and Anaiah, and Urijah, and Hilkiah, and Maaseiah, on his right hand; and on his left hand, Pedaiah, and Mishael, and Malchiah, and Hashum, and Hashbadana, Zechariah, and Meshullam.
5And Ezra opened the book in the sight of all the people; (for he was above all the people) and when he opened it, all the people stood up:
6And Ezra blessed the LORD, the great God. And all the people answered, Amen, Amen, with lifting up their hands: and they bowed their heads, and worshipped the LORD with their faces to the ground.
7Also Jeshua, and Bani, and Sherebiah, Jamin, Akkub, Shabbethai, Hodijah, Maaseiah, Kelita, Azariah, Jozabad, Hanan, Pelaiah, and the Levites, caused the people to understand the law: and the people stood in their place.
8So they read in the book in the law of God distinctly, and gave the sense, and caused them to understand the reading.**
It’s not off topic, since you’re explaining an interpretation of scriptures, as you understand it, to us…
