So Jesus had a temper tantrum because the prices were too high?
You still don't get it: lame animals were being sold. Only top line animals were to be used, because it was for God, not some stewpot. This was cheating God and saying you were great, parading your righteousness among men. It is one thing to charge stiff prices for Grade A, but for reject? And the poor were doing this because of sincerity of worship. The poor were willing to make the sacrifice, regardless of cost; but they should have been treated with respect, as well as God should have been respected.
The high prices were just insult to injury: the point is the sacrilege.
Does WT teach that Jesus was enraged because of dirty chicken feathers?
The chicken thing was extra-Biblical. If I recall the explanations it was post-dated against the Bbile. It was never mentioned in the Bible, at all. I'm not at all sure that the chicken was even "clean" or acceptable as a sacrifice. Have you ever watched a chicken eat in a barnyard? A lot of what was considered acceptable in an animal had to do with their eating habits and "relative clenliness". Doves were the bird that I recall being acceptable.
"sincerity of worship": this is something that you need to give deep consideration to. You find many of us here casting stones at JW's; but we still respect their sincerity of worship. We were there once; and we are generally somewhere in the "sincerity of worship" standard today, whatever that worship may consist of, now. I'm going to do a stretch here and say that even our Atheist posters are sincere in their worship (or lack thereof).
You are missing great expanses of meaning here, whiolesale.
