I was raised Methodist. My Great Great Grandfather donated the land for a local Methodist church in Alabama where all my line up to me are buried.
I have been on retreat at the Cistercian Trappist Abbey of Gethsemani. I watched the endless prayers at Vespers and got up at 3:AM to observe the monks at Vigils. I was a youth counselor at a Catholic Youth Home where I got used to calling a priest "Father" without being to uncomfortable. I even helped the boys learn their Rosary for Catechism, where I learned the words myself by heart.
That is as close as I'll ever get to praying the Rosary. I have no malice against it and I admire the traditional Mother Church for currently being a positive influence over humanity.
From being taught all your life to pray to "The Father, The Son and The Holy Spirit", it is to great a leap to now believe that Mother Mary will also put in a good word for you too. Additionally, Protestants believe also that the Apostles and Saints haven't interacted with mortal man since biblical times either.
In my Methodist Church we were taught to believe in “the communion of the saints.” We said the Apostle’s creed on regular Sundays and the Nicene creed on communion Sundays.
