The Lord's Supper

I was thinking today during mass about how it's at that momentous Passover before the crucifixion that the gospels record Jesus as "fully aware" that he was God's son, that he wouldn't be on earth much longer, etc. I was thinking about what it means to "drink the cup"--what it meant for Jesus and what it means for me, for all of us.
Next year at this time, I think I will be preparing to enter the Church.
