Baptism and the Holy Supper are the holiest acts of worship. Baptism
and the Holy Supper are as it were two gates, through which a man is
introduced into eternal life. After the first gate there is a plain,
which he must traverse; and the second is the goal where the prize is,
to which he directed his course; for the palm is not given until after
the contest, nor the reward until after the combat.
