1:1-9 All Christians are by baptism dedicated and devoted to Christ, and are under strict obligations to be holy. But in the true church of God are all who are sanctified in Christ Jesus, called to be saints, and who call upon him as God manifest in the flesh, for all the blessings of salvation; who acknowledge and obey him as their Lord, and as Lord of all; it includes no other persons. Christians are distinguished from the profane and atheists, that they dare not live without prayer; and they are distinguished from Jews and pagans, that they call on the name of Christ. Observe how often in these verses the apostle repeats the words, Our Lord Jesus Christ. He feared not to make too frequent or too honourable mention of him. To all who called upon Christ, the apostle gave his usual salutation, desiring, in their behalf, the pardoning mercy, sanctifying grace, and comforting peace of God, through Jesus Christ. Sinners can have no peace with God, nor any from him, but through Christ. He gives thanks for their conversion to the faith of Christ; that grace was given them by Jesus Christ. They had been enriched by him with all spiritual gifts. He speaks of utterance and knowledge. And where God has given these two gifts, he has given great power for usefulness. These were gifts of the Holy Ghost, by which God bore witness to the apostles. Those that wait for the coming of our Lord Jesus Christ, will be kept by him to the end; and those that are so, will be blameless in the day of Christ, made so by rich and free grace. How glorious are the hopes of such a privilege; to be kept by the power of Christ, from the power of our corruptions and Satan's temptations!
2. the church of God—He calls it so notwithstanding its many blots. Fanatics and sectaries vainly think to anticipate the final sifting of the wheat and tares (Mt 13:27-30). It is a dangerous temptation to think there is no church where there is not apparent perfect purity. He who thinks so, must at last separate from all others and think himself the only holy man in the world, or establish a peculiar sect with a few hypocrites. It was enough for Paul in recognizing the Corinthians as a church, that he saw among them evangelical doctrine, baptism, and the Lord's Supper" [Calvin]. It was the Church of God, not of this or of that favorite leader [Chrysostom].
at Corinth—a church at dissolute Corinth—what a paradox of grace!
sanctified—consecrated, or set apart as holy to God in (by union with) Christ Jesus. In the Greek there are no words "to them that are"; translate simply, "men sanctified."
called to be saints—rather, "called saints"; saints by calling: applied by Paul to all professing members of the Church. As "sanctified in Christ" implies the fountain sources of holiness, the believer's original sanctification in Christ (1Co 6:11; Heb 10:10, 14; 1Pe 1:2) in the purposes of God's grace, so "called saints" refers to their actual call (Ro 8:30), and the end of that call that they should be holy (1Pe 1:15).
with all that in every place call upon … Christ—The Epistle is intended for these also, as well as for the Corinthians. The true Catholic Church (a term first used by Ignatius [Epistle to the Smyræans, 8]): not consisting of those who call themselves from Paul, Cephas, or any other eminent leader (1Co 1:12), but of all, wherever they be, who call on Jesus as their Saviour in sincerity (compare 2Ti 2:22). Still a general unity of discipline and doctrine in the several churches is implied in 1Co 4:17; 7:17; 11-16; 14-33, 36. The worship due to God is here attributed to Jesus (compare Joe 2:32; Mt 4:10; Ac 9:14).
both theirs and ours—"in every place which is their home … and our home also"; this is added to include the Christians throughout Achaia, not residing in Corinth, the capital (2Co 1:1). Paul feels the home of his converts to be also his own. Compare a similar phrase in Ro 16:13 [Conybeare and Howson]. "Ours" refers to Paul and Sosthenes, and the Corinthians' home [Alford]. Beza better explains, "Both their Lord and our Lord." All believers have one and the same Lord (1Co 8:6; Eph 4:5); a virtual reproof of the divisions of the Corinthians, as if Christ were divided (1Co 1:13).
