I don’t know if this helps or not.
But I see just about 99 percent of Christian artists’ songs have to do with Gods Love, rather than Gods rule.
Rarely do I hear a song that says “Ooooo yeahhhh! Faith By Works is Wrong!!! OOOOOO"
"Dun dun dun… the body and blood are symbolic.”
How ever, that ijust as it is. I see protestant songs as leaving out the church and trying to fill the rest with God. Even though God gave the Church to us as well as his son.
I could be sounding really uneducated now, but that is how i learn. I say this all the time.
But I understand the Non-Catholic bands to sing an unfinished chorus. Leaving out some of the most important things.
Matt Maher is a great artist -
He sings about the Eucharist, Confession, and even the Pope!
However, i do not see listening to regular christian songs as a sin. Definitely Not. I would not be where i am without David Crowder, and yes i have thought of it as being a sin before, just never researched it. Good luck in finding a, hopefully, more well placed out answer.
God Bless you.
