have not read the article, but the 11 apostles (may be 12) were of the earthly class aka other sheep, at the time of partaking at the last supper. , and
the new covenant is for all members of the 12 tribes, whereas
the kingdom covenant is only for the 144 000 that are sealed out of them. similarly
all israelites were in the old Mosaic covenant only a few in the Davidic covenant for kingship.
if wt would listen to Jesus, they would repeat his words, eat, drink, all of you, this new covenant is about forgiveness of sins, later we will talk about another matter, the ruling. again.
wt still has not got that right, slow learners.
