I don't know what Protestants do, but we Christian non-Catholics don't repeat canned prayers.
Since God is our Father we talk to Him like that.
I guess without canned prayers that others wrote for them to vainly repeat, the average Catholic wouldn't have a clue what to do or say to God the Father. Our prayers are not incantations with the thinking that *Well, if we say this, the right way, often enough, and with enough "sincerity", then SOMEONE SOMEWHERE must have to hear and answer....*
What a gross misunderstanding of prayer Catholicism has.
