The apostle Paul teaches the vital importance of the gifted men whom Christ gave as gifts to the Church:
And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers; For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ: Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ: That we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive; But speaking the truth in love, may grow up into him in all things, which is the head, even Christ: From whom the whole body fitly joined together and compacted by that which every joint supplieth, according to the effectual working in the measure of every part, maketh increase of the body unto the edifying of itself in love (Eph. 4:11-16).
This teaching shows that the Church will only be all that it should be when it receives aright the ministry of all these men.
Paul lists evangelists among the gifted men whom Christ gave to His Church. Because Scripture names only Philip specifically as an evangelist, information about him in that regard has unique significance for the perfection of God’s people. Moreover, because only Acts 8 gives us specific information about his gospel ministry, it has unique significance for us in our understanding of gospel ministry.
A thorough assessment of Acts 8 makes clear that verse 12 gives us vital information because it reveals what Philip preached as the gospel:
BGT Acts 8:12 ὅτε δὲ ἐπίστευσαν τῷ Φιλίππῳ εὐαγγελιζομένῳ περὶ τῆς βασιλείας τοῦ θεοῦ καὶ τοῦ ὀνόματος Ἰησοῦ Χριστοῦ, ἐβαπτίζοντο ἄνδρες τε καὶ γυναῖκες.
SCR Acts 8:12 ὅτε δὲ ἐπίστευσαν τῷ Φιλίππῳ εὐαγγελιζομένῳ τὰ περὶ τῆς βασιλείας τοῦ Θεοῦ καὶ τοῦ ὀνόματος τοῦ Ἰησοῦ Χριστοῦ, ἐβαπτίζοντο ἄνδρες τε καὶ γυναῖκες.
NAU Acts 8:12 But when they believed Philip preaching the good news about the kingdom of God and the name of Jesus Christ, they were being baptized, men and women alike.
KJV Acts 8:12 But when they believed Philip preaching the things concerning the kingdom of God, and the name of Jesus Christ, they were baptized, both men and women.
Philip preached the gospel (euaggelizomai) about the kingdom of God and the name of Jesus Christ. For the Church of Jesus Christ today to be all that God would have it to be, it must profit fully from this revelation about the gospel according to Philip, the evangelist.
