1 Thessalonians 5:12-28
The holy kiss is mentioned four times in the New Testament as a common expression of affection, to be used as a greeting for Christians (Rom. 16:16; 1 Cor. 16:20; 2 Cor. 13:12; 1 Thess. 5:26). There was to be a ‘kiss’, or display of affection; but it was to ‘holy’ as well. They were to be careful that their greetings were genuine, and above reproach. There are at least two ways a kiss could be unholy. First, if it is not genuine, like the kiss of Judas (Luke 22:47-48) or Joab (2 Sam. 20:9). Second, if it is sexually motivated or gives the appearance of evil. Paul wanted to see affection between the saints, but he wanted it to be pure.
