Charles Bridges, in his justly celebrated work The Christian Ministry, gives some advice from Philip Henry on the administration of the Lord's Supper.
Philip Henry's was an admirable rule relative to this sacrament - 'so to manage it that the weak might not be discouraged and yet the ordinance might not be profaned.' Our instructions should have a direct reference to both these objects. We must not raise the standard too high for the humble, contrite, or scrupulous. Nor must we open the door for the admission of all.
