Calvin had studied Plato - no friend to Christianity - and is amused how accurately he depicted (in the Republic) the antics of medieval priests in celebrating the Mass - preying on the innocent and uneducated by fooling them into believing nonsense through magical "hocus pocus" conjuring tricks with bread and wine.
Private Communion (or Masses): Calvin is against them. True, he is against the Mass "period"; but mutatis mutandis he is against private celebrations of the Lord's Supper for the same reason: the Supper is meant to define the communion of the body, not its separation and individuality. As for the Mass itself: Calvin is subject to the antics of historic revisionists as much as we are in our time.
"Fear not, Abram: I am thy shield, and thy exceeding great reward."
In my last letter, I wrote that the Puritans show us how to marry doctrine and practice in our preaching. I'd like to add that they stressed the practice of piety (praxis pietatis), or practical godliness, flowing out of sound doctrine—just as much as Augustine and Calvin before them.
The Westminster Directory for Worship summarizes the Puritans’ commitment to sanctified application:
Olaudah Equiano – Waking Up Christians to the Evils of Slavery
John Chrysostom and Olympias – Finding Comfort in Troubled Times
Basic information – four ideas
