Absolutely - everything in its season. Just as you wouldn't tell jokes at a funeral, nor would you dress in black and act somber at a summer Church picnic.
The hard part is that we all use the same language to describe vastly different experiences. Both liturgical and non-liturgical strands of the faith refer to their gatherings as “church services”.
So, I can say a joke is appropriate in a “church service” — thinking non-liturgical in my head — and someone from a liturgical strand of the faith reads “church service” and — thinking liturgical in their head — marvels that I could possibly consider a joke to be proper in that context.
All because the same two words “church service” communicate widely disparate things to each of us.
Maybe, in Heaven, we’ll be able to think directly to each other so as to communicate 100% of what we mean without the inherent vagaries of the spoken word.
