The memorial I attended had a Bethel speaker. He was polished and actually easy to listen to...not that anything he said was any more coherent. There's only so much you can do when handed a pile of dung for a script...
He did carry on too much about the spring equinox thing, and how the date is confirmed. He recited the experience of some old anointed missionary who was in prison for years and years, and how he knew how to pick the proper date based on the moon phases. He obviously was in a John of Revelation state of mind, 'cause he observed the last meal by partaking of the emblems by nibbling on a piece of rice, and sipping whatever liquid he had.
This served two purposes: one - you too should know how to figure the memorial date on your own, you know, for when you're thrown in prison for your religious beliefs. Two - it impressed upon the weak minded, just how undeserving they are compared to this old guy who stayed faithful watching moon phases instead of digging a tunnel. If they want to be accepted by Jah, then they better be more like that deranged fool.
