I thought this was a Bible Church. You don't like the those fallen away Catholic pray. They have to pray like you do? That is kind of legalistic isnt it.Btw, we do not read prayers or recite prayers, we are encouraged to pray from what is in our hearts. We have another former catholic family in our class who are still struggling to shed their legalism.
Tell the preacher that you think the whole Church should stand up and say the the Lord's Prayer together this Sunday.
It would be a good wa of worhisping God together instead of a motivational speach from the minister.
