Revelation 1:10

was in the Spirit on the Lord's day.

Under the influence of the Spirit. The Lord's day is the day on which Christ arose from the dead, the first day of the week, as the Lord's Supper is the memorial of his death, and the term was also so used by the early Church. So Ignatius (about A. D. 101) and Chrysostom and Theodoret, who came later, use the term. It is remarkable that all of the appearances of the Savior after his death, of which we know the time, were on the Lord's day. There is, 1. That to Mary, to Peter, to the two disciples, and to the ten apostles on the first Sunday; 2. That to the eleven apostles on the second Sunday, one week later; 3. He sends forth the Spirit and founds the Church on the day of Pentecost, Sunday also; 4. And here he appears to John, his last appearance to mortals, on Sunday.
