Anyone who would react to Mary as if she were a goddess would be practicing evil. And what does the Bible say about this?
(1 Thessalonians 5:22 KJV) Abstain from all appearance of evil.
So since the scriptures do not demand that we kneel before statues and sing praises to Mary, and from an objective standpoint these practices appear to be idolatrous, therefore it is clear that the scriptures do command that we abstain from such behavior.
I agree.
If it gives the appearance of worshipping a goddess, then it is wrong.
That was precisely the argument of Paul regarding eating meat offered to idols. Sure, we're free to do what we want, but giving the appearance of idol-worship upends weak souls. He goes on to say that idols are nothing, but that there are demons behind them.
Paul saw a thin line between the spiritual world and this world.
"So since the scriptures do not demand that we kneel before statues and sing praises to Mary, and from an objective standpoint these practices appear to be idolatrous, therefore it is clear that the scriptures do command that we abstain from such behavior."
The Church disagrees, obviously. And The Church disagreed when it set out the canon of scripture.
