Monergism

"… no meeting of the church should take place without the Word, prayers, partaking of the Supper, and almsgiving" (Calvin's Institutes IV, xvii, p. 44).

"However, if we duly consider the end which our Lord has in view, we shall perceive that the use should be more frequent than many make it: for the more infirmity presses, the more necessary is it frequently to have recourse to what may and will serve to confirm our faith, and advance us in purity of life; and, therefore, the practice of all well ordered churches should be to celebrate the Supper frequently, so far as the capacity of the people will admit." (Calvin's Tracts, Vol. II, p. 179).
