It is almost 40 years now since I was baptized; it was in the month of May, but I don't remember the date. Anyway, back then there was never any clapping or cheering-- it was very solemn. We were even told by the pastor that when we turned around (either when coming to or going from the 'water zero') to turn our heads away from the congregation. I guess the idea was we might spot somebody out there that might make us smile. And he used the King James language: "...I baptize thee, my brother,..."
I suppose there was no applauding because it seemed to be considered unkosher to applaud anyone or anything in church then. Most churches we knew, that is. I remember that not long after that I was in this choir gathering that was in our church-- "junior choir" I was in, but I think there were youth choirs and others, too. But there was also some woman who sang a solo with a lot of range-- maybe she was there for a break, or one group needed more time to prepare; I don't know. But as she finished, the place broke into applause-- to may surprise and most of those around me. One guy, astonished, whispered, "You're not supposed to clap in church."
So I'm not certain what to think, sometimes, about the way we go about things today. On one hand, we cheer the person getting baptized, singing a solo, or whatever. On the other hand, we think very little about cheering kids or adults plalying a ball game-- do we consider that more 'cheerworthy' than baptism or singing songs of praise? Yet also, do we want our worship to appeal to the same emotions as a ball game? (and if not, to what should it appeal?)
