No doubt but it's simply a matter of convenience, not a requirement.The Bible says were to praise God with everything imaginable, including musical instruments, which would include an organ. Do you use musical instruments in your worship?
But it doesn't HAVE to include an organ. There's no Scripture that demands that music MUST be made with musical instruments.
On the contrary....
Colossians 3:16 Let the word of Christ dwell in you richly, teaching and admonishing one another in all wisdom, singing psalms and hymns and spiritual songs, with thankfulness in your hearts to God.
What does it matter of a group doesn't use instruments?
From what I read of church in the the Book of Acts, I am not sure that they're recognize what we do on Sundays here in America as church.
Wonder if those 'church building folk' realize their lungs and heart are organs.
Colossians 3:16 "Let the WORD of Christ dwell in you richly, teaching and admonishing one another in all wisdom, singing psalms and hymns and spiritual songs, with thankfulness in your hearts to God.
Seems some just glance at Scripture/God's Word while favoring what 'man' says. Catholicism and Calvinism - same mindset w/organized religion.
