Ephesians 1:1-2Paul, an apostle of Christ Jesus by the will of God, to the saints in Ephesus, the faithful in Christ Jesus: 2Grace and peace to you from God our Father and the Lord Jesus Christ.Letters in the ancient world followed a set form. They began by identifying the writer and the readers or addressees. This was usually followed by a greeting and a prayer or wish for health (even in secular letters), then the body of the letter, and finally the closing, which contained any details about the sending of the letter and another greeting. An example of this form appears in Acts 15:23-29 (without the prayer).Christian writers adapted this set form to their purposes, "christianizing" it by changing or expanding the traditional elements. The author and recipients are not merely identified; they are also described by their relation to Christ. The greeting was also made specifically Christian. Instead of merely "Paul to the Ephesians, greetings," Paul described himself as "an apostle of Christ Jesus by the will of God" and his readers as holy (NIV, "saints") and "faithful in Christ Jesus." And instead of using the standard word "greeting" [chairein], through a play on words Paul changed his greeting to read "grace [charis] and peace to you from God our Father and the Lord Jesus Christ."An apostle of Christ. Paul''s identification of himself as an apostle appointed by God is his customary way of beginning his letters. (Cf. the exact parallels in 2 Cor. 1:1; Col. 1:1; 2 Tim. 1:1.) Often Paul had to defend his legitimacy as an apostle, but here the tone is merely descriptive. The term apostle carried several connotations in the early church, all of which were true of Paul. It referred to someone who had seen the risen Christ (1 Cor. 9:1), to those sent out by the church with a missionary task, or more broadly to anyone who functioned as an agent or representative. This self-description emphasizes the authority with which Paul wrote. If he was an apostle because of the will of God, what he wrote must be seen as communication from God.The will of God is an important theme in Ephesians, appearing more frequently here than in any other letter. The concern is not about Christians finding the will of God; rather, the emphasis is on God''s purpose with his actions for humanity. The point here is that Paul was an apostle because God wanted him to be.In Paul''s letters, "Christ" (meaning "the Anointed One") is often no longer a title as it was in a Jewish context. Particularly among Gentile Christians it became a name, linked with the name "Jesus." But of the forty-six occurrences of the word "Christ" in Ephesians, twenty-three have the article in Greek, some of which may still point to the role of the Jewish Messiah in the salvation of the Gentiles (see 1:10; 2:13; 4:20).The Holy Ones. The identification of the recipients as "saints" (lit., "the holy ones") is Paul''s usual description of Christians. "Saints" is not a helpful translation, for this English word usually refers to extraordinarily pious people. Paul''s first intent was not that these people lived especially holy lives-he described the Corinthian Christians the same way (1 Cor. 1:2), and yet he had no illusions about the sanctity of their lives. Rather, his primary concern was to emphasize that just as he had been appointed by God to be an apostle, they too had been separated to God (separation is the key idea in the word "holy"). Paul''s addressees were holy because God had set them apart to be his people. The focus is entirely on God''s action and the reference is to God''s saving work.1The recipients2 of this letter are also described as "faithful in Christ Jesus" (cf. Col. 1:2). "Faithful" can refer either to someone who has proven to be faithful or to someone who is a believer, someone who has faith. The latter seems the better choice here (cf. John 20:27; Acts 10:45; 16:1, 15; 2 Cor. 6:15).With the expression "in Christ Jesus" we encounter one of the most significant and difficultKlyne Snodgrass is the author of 'The NIV Application Commentary: Ephesians', published 1996 under ISBN 9780310493402 and ISBN 0310493404.
