Paul arrived in Troas waited for the time the church would come together on the first day of the week to “break bread.” The term “break bread” in this context is understood by most scholars as a reference to partaking of the Lord Supper. So the church gathered to take the Lord Supper on the first day of the week. By all indications they met on Sunday evening – for it is clear in the text that Luke was using Roman time not Jewish time, for Luke calls the following morning – “the next day.” So here we have a clear example of the church coming together on the first day of the week, with the intended purpose of taking the Lord Supper – together. When compared with 1 Cor 16:2, and other similar allusions, plainly indicates that the Christian observance the first day of the week-afterward termed “The Lord’s Day” – was already a fixed practice of the churches. Why did the Christians worship on the first day of the week? Of course it was the first day of the week that our Lord rose. On successive Sundays, Jesus appeared to the apostles on the day he arose from the grave (John 20:19), Thomas being absent; and again on the following Sunday (Thomas present) (John 20:26) he appeared to them again. When the church began it was on Sunday – for Pentecost always begins on the first day of the week. For many reasons the first day of week became an important focal point of the Christian community!
