From The Divine Right of Church Government and Excommunication, followed by a letter of which Samuel Rutherford was a signatory.
God’s spirit works not with ceremonies, and so they are as the offering of swine’s blood, and the slaying of a man; and so [an] abomination to God, Isa. 66:1,2. The Holy Spirit is merited to us by Christ, Joh. 16:14. He shall receive of mine, and shew unto you: But who can say that the grace of joy in the Holy Ghost, wrought by the droning [continuous sound] of organs, and the holiness taught by the surplice [priestly robes], is a work of the spirit merited by Christ as our High Priest?… Now Altars, organs, Jewish ephods, or surplice, masse-cloaths [mass clothes], and Romish crossing, bowing to altars, images, [etc.] are badges of Jewish and popish religion.
from the Commissioners at London to the General Assembly (1644) by John Maitland, Alexander Henderson, Samuel Rutherford, Robert Baillie and George Gillespie (the Scottish delegates to the Westminster Assembly including Samuel Rutherford):
We cannot but admire the good hand of God in the great things done here already, particularly that the covenant, the foundation of the whole work, is taken, Prelacy and the whole train thereof extirpated, the service-book in many places forsaken, plain and powerful preaching set up, many colleges in Cambridge provided with such ministers as are most zealous of the best reformation, altars removed, the communion in some places given at the table with sitting, the great organs and Paul’s and Peter’s in Westminster taken down, images and many other monuments of idolatry defaced and abolished, the Chapel Royal at Whitehall purged and reformed; and all by authority, in a quiet manner, at noon-day, without tumult.
