And if you salute your brethren ... - The word “salute” here means to show the customary tokens of civility, or to treat with the common marks of friendship. See the notes at Luke 10:4. The Saviour says that the worst men, the very publicans, would do this. Christians should do more; they should show that they have a different spirit; they should treat their “enemies” as well as wicked people do their “friends.” This should be done:
- Because it is “right;” it is the only really amiable spirit; and,
- We should show that religion is not selfish, and is superior to all other principles of action.
