Greetings eby,
In response to the WT articles 1990, 1986:
the WT said: " 14 Jesus was not then discussing the emblems used in the Lord?s Evening Meal. That new celebration for Christians was not instituted until a year later, so even the apostles who heard Jesus in 32 C.E. knew nothing of it."
Just because Jesus didn't 'explain' it until a year later does not mean he didn't have it in mind when he said it. Many times he spoke things that are not, as though they were (Romans 4:17). There were many things our Lord said at present, the disciples did not understand until years later (Luke 9:48; Luke 22:26, 27; Luke 9:22; Luke 24:21). In the same way, when Jesus spoke of the eating his flesh and drinking his blood, a year later he SHOWED them that the flesh they eat is the bread (the bread of LIFE he mentioned in John 6:48) and the blood they drink is the red wine, not his physical flesh and blood (John 6:60). Thus, they understood that they were to do this in rememberance of him, and that this was the TRUE manna from heaven that he spoke of a year later. When Jesus was resurrected, they remembered that he used to say these things (John 14:26; John 15:27; John 2:22; John 12:16).
the WT said: "Only through forgiveness on the basis of Jesus? blood can we live forever."
This is true about the wine used at the Lord's evening meal. He said, "Drink out of it, all of YOU, for this is my blood of the covenant which is to be poured out in behalf of many for the FORGIVENESS OF SINS." (Matthew 26:28) The blood that Jesus spoke of in John 6:53 that the WT admits is the blood that forgives our sins is the wine that Jesus spoke of that anyone drinking it may have "the forgiveness of sins."
The time difference of a 'year' means nothing. Jesus is "the SAME yesterday, today, and FOREVER." (Hebrews 13:8). What he says now, is fulfilled later (John 14:29). What he said a year ago (John 6:53) is fulfilled a year later (Matthew 26:26-28).
the WT said: "Here, the ?vast mixed company? that shared with the Israelites in eating the manna in the wilderness foreshadow the great crowd of Jesus? ?other sheep? who, along with the anointed remnant of ?the Israel of God,? are now eating Jesus? flesh in a figurative sense. This they do by exercising faith in his sacrifice.?Galatians 6:16; Romans 10:9, 10."
The 'vast mixed company' that shared in the eating of the manna in the wilderness also entered INTO the covenant WITH Israel at Mount Sinai (Deuteronomy 29:10-12). Therefore, the great crowd also "enter into the [new] covenant" WITH Israel [of God] by partaking of the flesh of the Son of Man and drinking his blood.
