Beginning from the baptism of John - The words "beginning from" in the original refer to the Lord Jesus. The meaning may be thus expressed, "during all the time in which the Lord Jesus, beginning (his ministry) at the time when he was baptized by John, went in and out among us, until the time when he was taken up," etc. From those who had during that time been the constant companions of the Lord Jesus must one be taken, who would thus be a witness of his whole ministry.

Must one be ordained - It is fit or proper that one should be ordained. The reason of this was, that Jesus had originally chosen the number twelve for this work, and as one of them had fallen, it was proper that the vacancy should be filled by some person equally qualified for the office. The reason why it was proper that he should be taken from the seventy disciples was, that they had been particularly distinguished by Jesus himself, and had been witnesses of most of his public life, Luke 10:1-16. The word "ordained" with us has a fixed and definite signification. It means to set apart to a sacred office with proper forms and solemnities, commonly by the imposition of hands. But this is not, of necessity, the meaning of this passage. The Greek word usually denoting "ordination" is not used here. The expression is literally, "must one be, or become, γενέσθαι genesthai, a witness with us of his resurrection." The expression does not imply that he must be set apart in any particular manner, but simply that one should be designated or appointed for this specific purpose, to be a witness of the resurrection of Christ.

Beginning from the baptism of John - From the time that Christ was baptized by John in Jordan; for it was at that time that his public ministry properly began.

Must one be ordained - This translation misleads every reader who cannot examine the original text. There is no term for ordained in the Greek: γενεσθαι, to be, is the only word in the verse to which this interpretation can be applied. The New Testament printed at London, by Robert Barker, the king's printer, in 1615, renders this and the preceding verse more faithfully and more clearly than our common version: Wherefore of these men who have companied with us, all the time that the Lord Jesus was conversant among us, beginning from the baptism of John, unto the day he was taken up from us, must one of them Be Made a witness with us of his resurrection. The word ordained would naturally lead most readers to suppose that some ecclesiastical rite was used on the occasion, such as imposition of hands, etc., although nothing of the kind appears to have been employed.

Beginning from the baptism of John,.... Not from the time trial John first administered the ordinance of baptism; for Christ was not so soon made known, or had followers; but from the time of the administration of it by John, to Christ, when he was made known to Israel; and quickly upon this, he called his disciples, and entered on his public ministry: now Peter moves, that one who had been so early a follower of Christ, who had heard his excellent discourses, and seen his miracles, and who had steadfastly and constantly adhered to him, might be chosen in the room of Judas; one whose faith in Christ, love to him, and firmness of mind to abide by him, had been sufficiently tried and proved; who had continued with Christ and his apostles, from the beginning of his ministry, to that time: or as Peter adds,

unto the same day that he was taken up from us; by angels, and received by a cloud, and carried up to heaven; or "he ascended from us", as the Ethiopic version renders it; or "lifted up himself from us", as the Arabic version; for as he raised himself from the dead by his own power, by the same he could raise himself up from earth to heaven; the sense is, to the time of his ascension to heaven, whether by himself, or by the ministry of angels:

must one be ordained; there was a necessity of this, partly on the account of the above prophecy, and partly to keep up the number of the twelve apostles, Christ had thought fit to pitch upon; answering to the twelve tribes of Israel, and to the twelve gates, and twelve foundations of the new Jerusalem: and this choice or ordination was moved to be made, and was made, not by the other eleven apostles, but by the whole company of an hundred and twenty; for these are the persons addressed by the apostle, and to whom he said, as the Arabic version renders it, "one of these men ye must choose": and if the choice and ordination of such an extraordinary officer was made by the whole community, then much more ought the choice and ordination of inferior officers be by them: the end of this choice was,

to be a witness with us of his resurrection; the resurrection of Christ from the dead, which supposes his incarnation and life, and so his obedience, ministry, and miracles in it; and also his sufferings and death, with all the benefits and advantages thereof; and is particularly mentioned, because it not only supposes and includes the above things, but is the principal article, basis, and foundation of the Christian religion; and the sign which Christ gave to the Jews, of the truth of his being the Messiah; and was what the disciples were chosen to be witnesses of; and a principal part of their ministry was to testify it to men: and since this was their work and business, it was necessary that one should be chosen, and joined with them, who had been with them, and with Jesus, from the beginning, to the time of his ascension; and who was an eyewitness of his resurrection, that he might join with the apostles in their testimony.

Witness (μάτρυρα)

One who shall bear testimony: not a spectator, a mistake often made on Hebrews 12:1. Compare Acts 2:32.

Beginning from the baptism of John, unto that same day that he was taken up {u} from us, must one be ordained to be a witness with us of his resurrection.

(u) From our company.

1:21,22 Wherefore, etc. These verses set forth the necessary qualifications of an apostle. In order to be a witness, he must have (1) been a disciple of John, (2) left him in order to follow Jesus, (3) attended his ministry, and (4) seen him after his resurrection. He must be able to testify of all these as an eye witness.

1:22 To be a witness with us of his resurrection - And of the circumstances which preceded and followed it.

22. Beginning from the baptism of John-by whom our Lord was not only Himself baptized, but first officially announced and introduced to his own disciples.

unto that same day when he was taken up from us, must one be ordained to be a witness with us of his resurrection-How clearly is the primary office of the apostles here expressed: (1) to testify, from personal observation, to the one great fact of "the resurrection of the Lord Jesus"; (2) to show how this glorified His whole previous life, of which they were constant observers, and established His divine claims.

1:15-26 The great thing the apostles were to attest to the world, was, Christ's resurrection; for that was the great proof of his being the Messiah, and the foundation of our hope in him. The apostles were ordained, not to wordly dignity and dominion, but to preach Christ, and the power of his resurrection. An appeal was made to God; Thou, Lord, who knowest the hearts of all men, which we do not; and better than they know their own. It is fit that God should choose his own servants; and so far as he, by the disposals of his providence, or the gifts of his Spirit, shows whom he was chosen, or what he has chosen for us, we ought to fall in with his will. Let us own his hand in the determining everything which befalls us, especially in those by which any trust may be committed to us.
