2 John 1:3

Grace be with you, mercy, and peace, from God the Father, and from the Lord Jesus Christ, the Son of the Father, in truth and love.

Grace be with you, mercy and peace,.... This form of salutation, or wish and prayer for the blessings mentioned,

from God the Father, and from the Lord Jesus Christ, is the same used by other apostles; see 1 Timothy 1:2 and

See Gill on "Romans 1:7". Only it is added here with respect to Christ, that he is

the Son of the Father in truth and love; which is mentioned by the apostle to confirm the deity of Christ, which is plainly implied in wishing for the above things equally from him, as from the Father; and to oppose and confront some heretics of those times, who denied the true and proper sonship of Christ; and therefore he calls him, "the Son of the Father", the only begotten of the Father; and that "in truth", or truly and properly, and not in a figurative and metaphorical sense, as magistrates are called the sons of God, and children of the most High, by reason of their office; but so is not Christ, he is God's own Son, in a true, proper, and natural sense: and he is so "in love"; he is his well beloved Son, his dear Son, the Son of his love; as he cannot otherwise be; since he is not only the image of him, but of the same nature, and has the same perfections with him.
