Grace be with you - This is addressed to her, her household, and probably that part of the Church which was more immediately under her care.
The Son of the Father - The apostle still keeps in view the miraculous conception of Christ; a thing which the Gnostics absolutely denied; a doctrine which is at the ground work of our salvation.
Grace be unto you - See the notes at Romans 1:7. This salutation does not differ from those commonly employed by the sacred writers, except in the emphasis which is placed on the fact that the Lord Jesus Christ is “the Son of the Father.” This is much in the style of John, in all of whose writings he dwells much on the fact that the Lord Jesus is the Son of God, and on the importance of recognizing that fact in order to the possession of true religion. Compare 1 John 2:22-23; 1 John 4:15; 1 John 5:1-2, 1 John 5:10-12, 1 John 5:20.
In truth and love - This phrase is not to be connected with the expression “the Son of the Father,” as if it meant that he was his Son “in truth and love,” but is rather to be connected with the “grace, mercy, and peace” referred to, as a prayer that they might be manifested to this family in promoting truth and love.
