Yesterday I mentioned a theological rationale from church historian Justo Gonzalez for standing while receiving communion:
“At an earlier time, the practice was not to kneel for prayer on Sundays, for that is the day of our adoption, when we approach the throne of the Most High as children and heirs to the Great King.” — Justo L. González 
Gonzalez is writing specifically of prayer, but the rationale applies to receiving communion as well. As I mentioned yesterday those who want to kneel after receiving communion are welcome to go up to the altar rail and those who wish to receive communion while kneeling are invited to the weekly Wednesday communion service at 5:30 p.m.
I was reminded of this quote because although I had previously read his epic two-volume history of Christianity, the audio version recently became available and I’m enjoying the listen. I’m listening through my earbuds because making everyone in the office listen to it would probably constitute the creation of a hostile work environment.
