Christians worship God through Christ Jesus. That is all.
I wouldn’t bother, there is no talking to the Marian Worship Cultist. Catholicism I really don’t have issue with, many saved Catholics, but this veneration stuff has been fully debunked, defeated and destroyed by Protestant apologists for hundreds of years but like radical Muslims some Marian cultist stick stubbornly to their dogma. Before JPII this Marian stuff was a little out of style but he brought it back. Jesus said come straight to him for fellowship otherwise he will not know you...period, end of debate. I feel 100% sure in my salvation through Christ alone, I need no intercessor to speak for me, my source....um the scriptures..the infallible word of God, not the musings of some monk 100’s of years ago.
