1:9-11 It was the apostle's comfort that he did not suffer as an evil-doer, but for the testimony of Jesus, for bearing witness to Christ as the Immanuel, the Saviour; and the Spirit of glory and of God rested upon this persecuted apostle. The day and time when he had this vision was the Lord's day, the Christian sabbath, the first day of the week, observed in remembrance of the resurrection of Christ. Let us who call him Our Lord, honour him on his own day. The name shows how this sacred day should be observed; the Lord's day should be wholly devoted to the Lord, and none of its hours employed in a sensual, worldly manner, or in amusements. He was in a serious, heavenly, spiritual frame, under the gracious influences of the Spirit of God. Those who would enjoy communion with God on the Lord's day, must seek to draw their thoughts and affections from earthly things. And if believers are kept on the Lord's holy day, from public ordinances and the communion of saints, by necessity and not by choice, they may look for comfort in meditation and secret duties, from the influences of the Spirit; and by hearing the voice and contemplating the glory of their beloved Saviour, from whose gracious words and power no confinement or outward circumstances can separate them. An alarm was given as with the sound of the trumpet, and then the apostle heard the voice of Christ.

10. I was—Greek, "I came to be"; "I became."

in the Spirit—in a state of ecstasy; the outer world being shut out, and the inner and higher life or spirit being taken full possession of by God's Spirit, so that an immediate connection with the invisible world is established. While the prophet "speaks" in the Spirit, the apocalyptic seer is in the Spirit in his whole person. The spirit only (that which connects us with God and the invisible world) is active, or rather recipient, in the apocalyptic state. With Christ this being "in the Spirit" was not the exception, but His continual state.

on the Lord's day—Though forcibly detained from Church communion with the brethren in the sanctuary on the Lord's day, the weekly commemoration of the resurrection, John was holding spiritual communion with them. This is the earliest mention of the term, "the Lord's day." But the consecration of the day to worship, almsgiving, and the Lord's Supper, is implied in Ac 20:7; 1Co 16:2; compare Joh 20:19-26. The name corresponds to "the Lord's Supper," 1Co 11:20. Ignatius seems to allude to "the Lord's day" [Epistle to the Magnesians, 9], and Irenæus [Quæst ad Orthod., 115] (in Justin Martyr). Justin Martyr [Apology, 2.98], &c., "On Sunday we all hold our joint meeting; for the first day is that on which God, having removed darkness and chaos, made the world, and Jesus Christ our Saviour rose from the dead. On the day before Saturday they crucified Him; and on the day after Saturday, which is Sunday, having appeared to His apostles and disciples, He taught these things." To the Lord's day Pliny doubtless refers [Epistles, Book X., p. 97], "The Christians on a fixed day before dawn meet and sing a hymn to Christ as God," &c. Tertullian [The Chaplet, 3], "On the Lord's day we deem it wrong to fast." Melito, bishop of Sardis (second century), wrote a book on the Lord's day [Eusebius 4.26]. Also, Dionysius of Corinth, in Eusebius [Ecclesiastical History, 4.23,8]. Clement of Alexandria [Miscellanies, 5. and 7.12]; Origen [Against Celsus, 8. 22]. The theory that the day of Christ's second coming is meant, is untenable. "The day of the Lord" is different in the Greek from "the Lord's (an adjective) day," which latter in the ancient Church always designates our Sunday, though it is not impossible that the two shall coincide (at least in some parts of the earth), whence a tradition is mentioned in Jerome [Commentary on Matthew, 25], that the Lord's coming was expected especially on the Paschal Lord's day. The visions of the Apocalypse, the seals, trumpets, and vials, &c., are grouped in sevens, and naturally begin on the first day of the seven, the birthday of the Church, whose future they set forth [Wordsworth].

great voice—summoning solemn attention; Greek order, "I heard a voice behind me great (loud) as (that) of a trumpet." The trumpet summoned to religious feasts, and accompanies God's revelations of Himself.
