Let him say, ‘Come!’
And he that thirsteth—
Let him come!
And he that willeth—
Let him receive,
Freely, the water of life!”
We have also a positive acquaintance with the order of religious worship in the early Church, dating back one hardly knows how far, but definitely leading us into the custom of the first three centuries. Public services began, and were continued, as follows:
First, Prayer—or, possibly, a Salutation or Invocation, such as is in common use to-day.
Then the Reading of Scripture. The Old Testament and New Testament were both employed: the one being expounded to apply to the case of the Christian Church; and the other for her comfort, encouragement, and edification.
Then followed the Hymns and Psalms. The distinction appears to have been that the psalms were those of David; the hymns, such as the song of Mary, or of the angels; and the spiritual songs, such as were composed by private persons, or which sprang up spontaneously in a kind of chant. That this was liable to abuse, and might cause confusion, is made evident by Paul’s advice to the Corinthians. Between these acts of praise was interpolated some brief Scripture lesson. And, very likely, a considerable portion of time was taken up by this part of the service.
