So there is a HUGE debate between the deacons in my church about the psalm 150 response during lent. Some deacons say "A Isoos...". actually one deacon said it and now many follow him. Others say the same thing minus the A so bascially some people add an A before the response. Is this correct/acceptable? I don't think it is...I thought the A was there as a place holder something but someone actually put an alpha before isoos on our lenten powerpoint.
