Albert Barnes on Luke 14:26

And hate not. The word hate, here, means simply to love less. See the meaning of the verse in Mt 10:37. It may be thus expressed:

"He that comes after me, and does not love his father less than he loves me, &c., cannot be my disciple."

We are not at liberty literally to hate our parents. This would be expressly contrary to the fifth commandment. See also Eph 6:1-3; Co 3:20. But we are to love them less than we love Christ; we are to obey Christ rather than them; we are to be willing to forsake them if he calls us to go and preach his gospel; and we are to submit, without a murmur, to him when he takes them away from us. This is not an uncommon meaning of the word hate in the Scriptures. Comp. Mal 1:2,3; Gen 29:30,31; De 21:15-17.

(v) "and hate not his father" De 33:9, Mt 10:37 (w) "his own life" Acts 20:24, Rev 12:11
