Right now my church band seems to be in need of a bassist. I thought it'd be neat to try, since the songs they play don't seem to be overly hard, and they mainly need a bass to keep a steady beat and help out the lead guitarist.

What's the learning curve though? I don't want to try this and completely fail everyone haha. From what I've seen and heard, the slower songs seem to be easier since I'd just be strumming one string over and over before moving onto another. So I guess like chords, but with one string haha.

My only musical experience is years of piano (got to level 7 I think?), and playing tuba and baritone, though I doubt that counts for anything.

its easier than piano for sure. around the same as guitar. it's boring at first since its all following the root note but once you get better and get used to making basslines then its fun.

u can choose to play using your fingers or pick, but fingers just look so much cooler LOL.

That's all I need to do though, play root notes haha, since the songs they play aren't overly hard.

As a bassist, you're sharing responsibilities with the drummer to hold the fort down with regard to the beat/rhythm/timing of the song. If all you're doing is playing the root note of each chord progression, your role would be fairly straightforward. However you may get bored rather quickly, which is why bassists add their own flare by composing a melodic line that compliments the song just as a drummer plays fills.
