Participatory church? I do that.
I sit and stand when the worship leader tells me to and sometimes even sing along, do the happy clap or raise my arms with my eyes closed when prompted;
I shake hands with the guy in the pew ahead of me when the associate pastor says to greet one another;
On occasion I say “amen” when the senior pastor asks us to say “amen” during his sermon;
I put money in the plate when its passed down my row by the ushers; and
I even bow my head when told to do so during the invitation for folks to raise their hands and receive Jesus.
So yes, I participate when I go to church, thank you very much!
