1 Thessalonians 5:26
Greet all the brothers with an holy kiss.
Shake hands with somebody as you go out of church. The more of it the better, if it is expressive of real interest and feeling. There may be a great deal of the spirit of the gospel put into a hearty shake of the hand. Think of St. Paul's four times repeated request, "Greet one another," after the custom then in common use, and one which is expressive of even warmer feeling than our common one of hand shaking. Why not give your neighbours the benefit of the warm Christian feeling that fills you to your finger tips, and receive the like from them in return? You will both be benefited by it; and the stranger will go away feeling that the church is not, after all, so cold as he had thought it to be.
