Revelation 1:10

On the Lord's day. [3] Not on the Jewish sabbath, which is our Saturday, but on the Christian sabbath, our Sunday, called the Lord's day. The Church, in the apostle's time, changed the day of rest, on which the Jews were commanded to rest and sanctify that day, from Saturday to Sunday, from the last day of the week to the first. They judged this only to be an indispensable precept, that some day or some time should be appointed, in a special manner, to God's service and worship, on which Christians should also abstain from servile works, that were not of necessity: as to the determination of such a day of the week, they judged that the Church had power to change the day. The late pretended reformers have all agreed with us in this change. And if they would have all that is expressed in this commandment, to be of an indispensable and unchangeable obligation, according to the letter of the law, they ought certainly to observe, to sanctify, and to abstain from all servile works of Saturday, or on the Jewish sabbath. --- A great voice, as of a trumpet. To signify the importance of things to be revealed. (Witham) --- Voice, &c. This was most likely St. John the Baptist, who calls himself the voice of one crying in the desert, and who in Malachias is called the Angel of the Lord, as he is also styled in the first verse of this chapter. (Pastorini)
