Worst-ever metaphor for church?

ISTM there couldn’t be a much worse metaphor for being the church than,

I’se The B’y that builds the boat and
I’se The B’y that sails her and
I’se The B’y that catches the fish and
Brings ’em home to Liza

ISTM that in this case, “Liza” (or God, in the metaphor) might just respond,

I don’t want your maggoty fish
They’re no good for winter
Well I can buy as good as that,
Way down in Bonavista!
