I only ask because I dont see the point in going to a party where I am denied access to the buffet.
It's worse. You're invited to the party and they pass round the food and drink under your nose but you've been told it's not for you and can't accept anything.
The old Mosaic Law was more inclusive toward Gentile proselytes than the JW system. They could literally partake of the Passover lamb; they could literally partake of the communion sacrifice with the priests. The 'alien resident' was to be treated the same as the native Jew.
w04 5/15 p. 21 par. 3 Highlights From the Book of Leviticus
Some of the offerings and sacrifices of the Law were voluntary, whereas others were compulsory. The burnt offering, for example, was voluntary. It was presented to God in its entirety, even as Jesus Christ willingly and wholly gave his life as a ransom sacrifice. The voluntary communion sacrifice was shared. One part of it was presented to God on the altar, another portion was eaten by the priest, and still another by the offerer. Comparably, for anointed Christians, the Memorial of Christ’s death is a communion meal.—1 Corinthians 10:16-22.
Yet, the "spiritual Gentiles," and converts to Christianity, i.e. the "other sheep," CANNOT even symbolically partake of the ultimate Communion Sacrifice (thus sharing it with the "spiritual priests") or Passover Lamb, despite that sacrifice being meant for everyone. The JW system is a step backward from the Mosaic Law rather than it harmonizing with the intentions of Christianity which was to be MORE inclusive and break down divisive walls!
