Well, as the preterist minority here I have been quite busy lately - plus I was able to land a part-time job at the health clinic.(yay!)
As far as taking Communion past the Lord's Coming- I know I do simply bc Jesus said to "do this in remembrance of Me."
As far as any time limits on the "body & blood" elements- I will refer you to the general preterist pov:
"Our point is that in I Corinthians 11:26 when Paul told the Corinthians "ye do shew forth the Lord's death until he come," that it was simply another example of inspired testimony that the Lord would return in the generation then living! If this is not the meaning of the words and text then ask yourself this question: If the Lord had wanted to tell the Corinthians they would take of the Supper until he returned how better could it have been expressed than it is already in verse 26?
A further short thought on "until." It need not be thought that the word is always used in the sense of "up to the point of and not after." Very often in scripture the word is used in a transitional sense without the sense of termination.
In Matthew 11:12 Jesus said the kingdom had suffered violence "until now." Did the kingdom suffer no violence after the days of John the Baptist? In verse 13 of the same text Jesus said the "Law and prophets were until John;" did the law pass away when John came? In Romans 5:13 inspiration says sin was in the world "until the law." Now was there no more sin after the Old Law came? Paul told Timothy "until I come give attendance to reading, exhortation, to doctrine," I Timothy 4:13. Was Timothy to stop the public reading of scriptures and doctrinal preaching when Paul came? Incidentally the correspondence of I Timothy 4 and the language of I Corinthians 11:26 is remarkable.
These few examples should demonstrate that we need not necessarily understand the word "until" in I Corinthians 11 as indicating an end to the institution of the Lord's Supper."
