John Calvin on 1 Corinthians 14:28

28. Let him speak to himself and to God “Let him enjoy,” says he, “his gift in his own conscience, and let him give thanks to God.” For in this way I explain the expression to speak to himself and to God, as meaning — to recognize in his own mind with thanksgiving the favor conferred upon him, “Le benefice et don de Dieu;” — “The kindness and gift of God.” and to enjoy it as his own, when there is not an opportunity for bringing it forward in a public manner. For he draws a contrast between this secret way of speaking, and speaking publicly in the Church — which he forbids. “En ce cas;” — “In this case.”
