This isn’t really a “Who Said That” or a “Guess the Good Guy.” The quote is obviously from a document. So, can you guess which document (original source)?
It is directed that the Lord’s Supper shall be administered in the larger towns at least once a month and in villages once in two months, and in either case always on Christmas, Easter, and Whitsuntide. As the edification of the Church may require, it is Christian and right to celebrate it oftener.
Don’t be a cheater.
Here’s the answer to this short-lived game: This is an excerpt from the Palatinate Liturgy, originally written in the same year as the Heidelberg Catechism, 1563, by Casper Olevianus. The Liturgy, printed with the Catechism for the churches, served to “provide for and represent the worship of the Church as the Catechism did its doctrine.” –(from Creed and Cultus, 1863).
I found (most of?) the liturgy in the above linked Tercentenary Monument from the Reformed Church in America. (If anyone has a link to a stand-alone copy of the Palatinate Liturgy let me know).
Also of note: I noticed that the prayers used in the sacrament of baptism are virtually unchanged in our churches today. I also liked the confession and absolution which include this declaration spoken by the minister, “I announce, by the command of God, that they are released in Heaven from all their sins.”
