MCGI believes that holy kiss can be sent through letters as exemplified in ROM 16:16 the churches of christ salute you. As you can see we can salute with a holy kiss, that is, a greetings of peace/charity wherein we could salute through letters as exemplified by the churches widespread in the world has greeted roman christians in Rome through Paul’s letter to the romans as it say: the churches of Christ salute you. This greeting was by letter. Therefore it is not a physical affection greeting such as INC’s beso beso or handshake bec it could be sent through letters.
Biblically, holy kiss is a kiss of charity, as mentioned in 1PETER5:14 and it is likewise a greeting of peace when used as a greeting as the verses above implied. So greeting with holy kiss is a greeting of peace.
1 Corinthians 16:19-21
The churches of Asia salute you. Aquila and Priscilla salute you much in the Lord, with the church that is in their house.
All the brethren greet you. Greet ye one another with an holy kiss.
The salutation of me Paul with mine own hand.
As we can see, the churches of Asia sent greetings of holy kiss through Paul’s letter. Likewise, the early christians greet through Paul by saying, all the brethren greet you (with a holy kiss). That is a salutation or greeting as Paul said, and again, it was through a letter, or it could be by saying, peace be unto you as Jesus used, as it say:
That is a conduct as example that we must necessarily follow as it say:
These are the only christian greetings supplied in the bible. The only greeting of peace so as suggested, so should we exceed it to add beso beso or handshake? Or nose to nose, if preferred? Etc…?
Therefore greeting with holy kiss is either a verbal or written greeting ascribed to a christian where the only supplied way is to say:
“I greet you with a holy kiss” or “the brethren greets you” or “the churches of christ greets you” or it could be jesus way: “peace be unto you”
Holy kiss as apparent symbol of peace/charity.
There is only one way of greeting required by god and that is through holy kiss. Peter specified it for the whole church.
1 Peter 5:14
Greet ye one another with a kiss of charity. Peace be with you all that are in Christ Jesus. Amen.
Therefore, the only way to do it is through the aforementioned concept. Lastly, my answers are my own concept and not necessarily representing MCGI.
