Charles Ellicott Commentary John 15:23

"He that hateth me hateth my Father also." — John 15:23 (ASV)

He that hateth me hateth my Father also.—Compare Note on John 5:23, and John 15:18 in this context. Again the darkness of the world’s hatred is drawn in the successive degrees of sin. Hatred against the disciples is hatred against the Master whom they represent. Hatred against the Son is hatred against the Father whom He represents. Hatred of the Father! There can be no greater darkness.

The sinfulness of sin has in this thought reached its limit. God is love. The heart that can hate love has hardened itself, and cannot be loved.
