Thanks, ,BD. I have been on CARM since late January 2000. So, waaaaaay longer than you.
But all of this timing when the paschal lamb was slaughtered is just a big hoopla over nothing. My synod has no official doctrine about the timing and anyway, who cares, anymore? The lamb in Jesus' day was slaughtered so He and His disciples could celebrate the Passover one last time, in which He instituted the Lord's Supper. Jesus didn't seem to care when it had been slaughtered at all, and nothing was said about that. His focus was on other things entirely. So should our focus be!
