I don't mean to be a stick in tha mud, but my music teacher (when I was taking classes) told me that most gospel songs won't be found in store tabbed for you already. He told me that I could develop my ear if I could listen to a song and figure out the notes and chords.
most gospel songs will have the same progression in them. If the song sounds like a rock song (Tye Tribbett - no other choice) then it's a more rock progression than a gospel one. ( I almost had the song figured out until I remembered that someone posted the chords 
)
But I won't leave you without a solution 
I don't know if you heard about hearandplay.com, but Jermaine Griggs give alot of progression used in gospel. If you have a good background on theory, you can transpose alot of stuff from the piano onto the guitar. I guarantee you that when you play the same thing the organist is playing, everyone will look at you different. 
Also it helps to get in good with a pianist willing to show you things 
I agree 100% with your view.
The problem I've run into is two-part.
1. I have a keyboard player that doesn't feel guitar is needed. I question chords and chord movement. I'm a general pain in the butt because I don't want to "make it through" Sunday service. I get NO help from him and he can't tell you what he's playing in musical terms anyway, it's all habit and mechanical repetition to him.
2. Getting up to speed on those "same progressions" isn't easy unless you have some base to initially learn them from. I'm finding progressions repeated or turned upside down all through this music....but first I needed to see them correctly laid out.
You WON'T find gospel songs in stores tabbed because there is so little guitar IN gospel music. We're largely left to find our own way. Anything claiming to have "guitar chords" are usually more harm than good.
I could have existed quietly with my wah and volume pedals adding beautiful swells and color work behind the piano player, but I've chosen to up my OWN game by bringing complementary acoustic and nylon guitar to work alongside the piano. For this I NEED real progressions I can walk in with and if the keyboard player is being lazy or just relying on old habits, I need to be RIGHT if I'm going to argue for a change in that song.
This keyboard sheet music is NOT always correct, but is considered along with my ear in developing the best recipe I can cook up. I'm in a position of guerilla warfare in my quest for excellence...I'll use ANYTHING that might help in my small battle.
It's strange, but I'm starting to learn to play the entire song in jazz style by myself, but I understand that I need to almost forget it all on Sunday to do condensed versions that will fit with a keyboard that's taking up most of the sonic space. Still, knowing the bigger chordal picture allows me some great ideas of upper voice movement that sit perfectly with piano or Hammond organ.
I actually got one of my highest complements by way of the bass player this week for my efforts. Last Sunday, I saw our bass player talking closely to a visiting keyboard player from another church. They are old friends.
I saw the visitor eyeing me suspiciously after service and saying something to our bass player, followed by the bass player turning to see me looking back....at which point the bass player sorta laughed.
I later asked the bass player if they were talkin' about me and he seemed reluctant to tell me what was said.
I prodded about what that keyboard player had said and the bass player sorta smiled sheepishly and asked, "Do you REALLY want to know EXACTLY what he told me?"
"He said:
'White Boy BAAAAAD!'"
