On examining the Scriptural reasoning cited in the passage below, should our conscience allow us to invite people to be "observers" at a ritual which presents falsehoods as truth?
The evening before Jesus died, he instigated a new covenant which was to be celebrated with wine and unleavened bread. This would replace the old covenant. He told his followers to 'keep doing this in remembrance of me'. When Jesus replaced the Law Covenant with the New Covenant, he plainly explained to all 12 of his apostles, Judas included, that they were to drink the wine because "this means my ‘blood of the covenant,’ which is to be poured out in behalf of many for forgiveness of sins".(Matthew 26:28) He said that his "blood of the covenant" was to be poured out in behalf of many, not just 144,000. Once Judas had partaken of the emblems of the New Covenant, Jesus dismissed him, and only then concluded a separate covenant, one for a kingdom. (Luke 22:17-30) Like Moses, Jesus did not use any emblems or ritual to inaugurate the priesthood covenant. Participants of the new covenant, through Jesus' sacrifice, have their sins forgiven permanently by Jehovah and have the hope of everlasting life, either on the earth or in heaven as priests. (Heb. 10:12) Having an understanding of the covenants helps to make crystal clear the simplicity of Jesus' words at Luke 22:30 and John's words at Revelation 7:4 concerning those taken out of Israel to judge those who are left. We are all sons of God through our faith in Jesus Christ, (Matt. 5:9; Matt. 6:9; Mark 3:35; Luke 8:21; John 1:12; John 15:13-15; Rom. 8:14; Rom. 5:19; 2 Cor. 6:17; Galatians 3:26; Rev. 7:4) because all who have been baptized into Christ (Matthew 28:19) have put on Christ. (Galatians 3:27) Jesus also said that those who do the will of God are his brothers. (Matthew 12:50) These scriptures reflect each other, for since Christ is the son of God (Mark 3:11, John 1:34) and we are sons of God as well, this would make us brothers to Christ. That is why we address Jehovah as "our Father".
