“Greet all the brothers and sisters with a holy kiss.” 1 Thessalonians 5:26
The first book in the New Testament is the Gospel of Matthew but it is not the first Christian writing. Paul wrote 1 Thessalonians and it was the first Christian writing, dating to about 49 C.E. Paul wrote this epistle about 20 years after Jesus’ death and about 20 years prior to the first Gospel (Mark) in the New Testament.
How many of you greet your fellow Christians with a holy kiss?
