When I officially decided to convert to the Catholic Church, I had several key concerns. So I went to the senior Pastor at the area parish. One of the questions I asked was: ** are Catholics ever “required” to pray to someone other than God. The Priest said “absolutely not.”**
He also said, it is not required to pray the rosary, and if you do obtain and use rosary beads, there are many alternate prayers that do not invoke anyone other than God (i.e., the Jesus Prayer, the Our Father, the Doxology, etc.).
Personally, I have no issues with the standard Hail Mary devotions (or the 4 official Marian dogmas), but there are several Marian devotions I refrain from and I draw the line at the 5th doctrine if “Co” is misapplied to mean Associate versus Assistant or Helper.
Hope this helps.
