Just for the record since I play drums/guitar/bass in my church band (small church..utility is key.....) and really, key to most church songs are to know the chords: G, C, D, F, A and E. Generally speaking in open configeration and major chords. That'll get you most church songs...and a whole lotta other pop/rock songs too!
To my GT Admins and instructor friends; worship songs might be worth considering. It is a huge market and a segment looking for new songs to add to their services. My little church, we add often. Food for thought.
