Am I the only one who notices a couple of problems with this?
First of all, Passover is on 15 Nisan, not 14.
The sheep should prove to be sound, a male, a year old, for YOU. YOU may pick from the young rams or from the goats. And it must continue under safeguard by YOU until the fourteenth day of this month, and the whole congregation of the assembly of Israel must slaughter it between the two evenings. And they must take some of the blood and splash it upon the two doorposts and the upper part of the doorway belonging to the houses in which they will eat it. “‘And they must eat the flesh on this night. - Exo 12:5-8
The Jewish day is from sundown to sundown. The lamb is to be slaughtered on the 14th and eaten "this night", which would be after sundown, or the 15th. Passover this year starts on Tuesday (Monday after sundown) and Jehovah's Witnesses are celebrating the Memorial on Sunday after sundown (14 Nisan) - a full day before Passover.
Secondly, there is no scriptural reason to believe Judas had left before the bread and wine were eaten.
Also, he took a loaf, gave thanks, broke it, and gave it to them, saying: “This means my body which is to be given in YOUR behalf. Keep doing this in remembrance of me.” Also, the cup in the same way after they had the evening meal, he saying: “This cup means the new covenant by virtue of my blood, which is to be poured out in YOUR behalf. “But, look! the hand of my betrayer is with me at the table. - Luke 22:19-21
he, knowing that the Father had given all things into [his] hands and that he came forth from God and was going to God, got up from the evening meal and laid aside his outer garments. And, taking a towel, he girded himself. - John 13:3-4
Therefore, after he received the morsel, he [Judas] went out immediately. And it was night. - John 13:30
Matthew and Mark discuss the Last Supper, but do not mention Judas leaving before the bread and wine are passed. Since 2 of the Gospels make it clear that Judas was present during the passing of bread and wine, the matter should be considered established. Notice, how the Watchtower site jumps from Gospel to Gospel to establish their timeline, taking events out of context and piecing them together as they see fit .
How are mistakes this seemingly simple made by people who are supposed to be "Jehovah’s spirit-directed organization" and "his sole visible channel, through whom alone spiritual instruction was to come"? The sad part is, they are so arrogant and so self-absorbed, if these points are brought to their attention, they will ignore them and turn you in to your local elders. To add insult to injury they may actually reply, sending a condescending copy-and-paste letter back to you that would insult the intelligence of a goldfish. Of course, this letter would only reference their own writings and carefully avoid any scriptural references.
