2 Corinthians 1:3

εὐλογητὸς ὁ Θεὸς κ. τ. λ.: blessed is the God and Father of our Lord Jesus Christ. Note that τοῦ Κυρίου is dependent on Θεός as well as on πατήρ; cf. Ephesians 1:17, and John 20:17; Revelation 1:6. This is the starting-point of the Christian revelation, that the Supreme is “the God and Father” of Jesus Christ; He is εὐλογητός (בָּרוּךְ), the Object of His creatures' blessing. The verb is not expressed, but the analogy of 1 Peter 4:11 would indicate that ἐστίν rather than ἔστω should be understood. A doxology is not a prayer, but (cf. Matthew 6:13, and John 12:13, a close parallel) a thankful and adoring statement of the Divine goodness and power. ὁ πατὴρ τῶν οἰκτιρμῶν : the Father of mercies, sc., from whom merciful acts proceed; οἰκτιρμός, compassion, is the very characteristic of a Father's providence; see reff. and Luke 6:36. καὶ Θεὸς πάσης παρακλήσεως : and God of all comfort, sc., from whom every consolation proceeds. We have παράκλησις applied to God in O.T., e.g., in Ps. 93:19, αἱ παρακλήσεις σου ἠγάπησαν τὴν ψυχήν μου; and the word is adopted in the N.T. for the Divine comfort not only by St. Paul (see reff.), but by St. Luke (Luke 2:25 and Acts 9:31), and by St. John, who describes alike the Spirit (John 14:16; John 15:26; John 16:7) and the Son (1 John 2:1) as the παράκλητος.
