1 After his salutation and thanksgiving1
1:1 Paul, called to be an apostle - There is great propriety in every clause of the salutation, particularly in this, as there were some in the church of Corinth who called the authority of his mission in question. Through the will of God - Called "the commandment of God", Ti1 1:1. This was to the churches the ground of his authority; to Paul himself, ofan humble and ready mind. By the mention of God, the authority of man is excluded, Gal 1:1; by the mention of the will of God, the merit of Paul, Co1 15:8, etc And Sosthenes - A Corinthian, St. Paul's companion in travel.It was both humility and prudence in the apostle, thus to join his name with his own, in an epistle wherein he was to reprove so many irregularities. Sosthenes the brother - Probably this word is emphatical; as if he had said, Who, from a Jewish opposer of the gospel, became a faithful brother.
1:2 To the church of God which is in Corinth - St. Paul, writing in a familiar manner to the Corinthians, as also to the Thessalonians and Galatians, uses this plain appellation.To the other churches he uses a more solemn address.Sanctified through Jesus Christ - And so undoubtedly they were in general, notwithstanding some exceptions. Called - Of Jesus Christ, Rom 1:6. And - As the fruit of that calling made holy.With all that in every place - Nothing could better suit that catholic love which St. Paul labours to promote in this epistle, than such a declaration of his good wishes for every true Christian upon earth. Call upon the name of our Lord Jesus Christ - This plainly implies that all Christians pray to Christ, as well as to the Father through him.

1:29 He seeth Jesus coming and saith, Behold the Lamb - Innocent; to be offered up; prophesied of by Isaiah, Isa 53:7, typified by the paschal lamb, and by the daily sacrifice: The Lamb of God - Whom God gave, approves, accepts of; who taketh away - Atoneth for; the sin - That is, all the sins: of the world - Of all mankind. Sin and the world are of equal extent.
1:31 I knew him not - Till he came to be baptized. How surprising is this; considering how nearly they were related, and how remarkable the conception and birth of both had been. But there was a peculiar providence visible in our Saviour's living, from his infancy to his baptism, at Nazareth: John all the time living the life of a hermit in the deserts of Judea, Luk 1:80, ninety or more miles from Nazareth: hereby that acquaintance was prevented which might have made John's testimony of Christ suspected.
1:34 I saw it - That is, the Spirit so descending and abiding on him.And testified - From that time.

49:3 O Israel - As the name of David is sometimes given to his successors, so here the name of Israel may not unfitly be given to Christ, not only because he descended from his loins; but also because he was the true and the great Israel, who, in a more eminent manner, prevailed with God, as that name signifies, of whom Jacob, who was first called Israel, was but a type.
