If you study what the apparitions have said in their various appearances you will quickly see their message is a false one.
Whether they're praying to it or not is not the primary issue.....though it is an important one.
If one is kneeling before a statue they are showing subservience to it.....it is an act of worship.
It has come before Christ. No where in the NT do believers kneel before anyone or anything.
In Revelation we have this encounter between John and an angel...bolded emphasis mine :
8I, John, am the one who heard and saw these things. And when I heard and saw, I fell down to worship at the feet of the angel who showed me these things. 9But he said to me, Do not do that. I am a fellow servant of yours and of your brethren the prophets and of those who heed the words of this book. Worship God. Revelation 22:8-9 NASB
as I said, I am not going to study anything. I’m out.
