Although the Reformed Churches are best known for singing the Psalms, other biblical canticles have played a role in Reformed liturgies in several settings. Here is article 69 of the Church Order of Dort of 1618:
In the Churches only the 150 Psalms of David, the Ten Commandments, the Lord’s Prayer, the Twelve Articles of Faith [Apostles' Creed], the Song of Mary, that of Zacharias, and that of Simeon shall be sung. It is left to the individual Churches whether or not to use the hymn “Oh God! who art our Father.” All other hymns are to be excluded from the Churches, and in those places where some have already been introduced they are to be removed by the most suitable means.
The hymn, O God! who art our Father, seems to refer to a metrical paraphrase of the Lord's Prayer, possibly a reference to this familiar elaboration of the biblical text.
