1 Corinthians 16:19,20

“The Churches of Asia salute you. Aquila and Priscilla salute you much in the Lord, with the Church that is in their house. 20. All the brethren greet you. Greet ye one another with an holy kiss.”

Asia denotes the province of that name, proconsular Asia which embraced the whole south-west region of Asia Minor and even Phrygia. The apostle no doubt frequently saw at Ephesus representatives of the numerous Churches founded in those parts; or he even visited them himself; comp. Acts 20:25. He might thus have been really charged by them with these salutations. It may be assumed that among them were those of Colosse, Hierapolis, and Laodicea.

The special salutation of Aquila and Priscilla is easily explained if we bear in mind that they had previously been settled with Paul at Corinth, and that they had assisted in founding the two Churches of Corinth and Ephesus. The Church assembled in their house undoubtedly comprehended not only their own family and workmen, but also all those Christians of Ephesus who had their central place of worship in this house. The κατά is distributive, and indicates that there were other houses at Ephesus where the Christians who dwelt in other quarters of the city met together. There must thus have been various places of assembling in the great cities such as Ephesus, Corinth, or Rome. There is no certain example of the existence of special buildings devoted to Christian worship within the territory of the Roman Empire before the third century (Edwards).

The third salutation is addressed by all the brethren, members of the Church of Ephesus. One feels in reading such salutations, that the history of nations is coming to an end, and that of a new nation of a wholly different kind is beginning.

This manifestation of love, on the part of the other Churches, should rekindle brotherly love among all the members of the Church which is its object; and this fire of charity which glows in their hearts should show itself outwardly in the brotherly kiss, according to the usage received among the first Christians. In the time of Justin this rite was celebrated between prayer and the Holy Supper. It is said that the president of the assembly kissed the nearest brother, and so in order, while the women on their side did the same. In this case we have to imagine the ceremony taking place at the moment when the congregation finished the reading of this letter. It is a commission, as it were, which the apostle gives them one to another.
