thoughts, in the Second, that of our mouth in words, in this
Third is prescribed our attitude toward God in works; and it is
the first and right table of Moses, on which these three
Commandments are written, and they govern man on the right side,
namely, in the things which concern God, and in which God has to
do with man and man with God, without the mediation of any
creature.

The first works of this Commandment are plain and outward, which
we commonly call worship, such as going to mass, praying, and
hearing a sermon on holy days. So understood there are very few
works in this Commandment; and these, if they are not done in
assurance of and with faith in God's favor, are nothing, as was
said above. Hence it would also be a good thing if there were
fewer saint's days, since in our times the works done on them are
for the greater part worse than those of the work days, what with
loafing, gluttony, and drunkenness, gambling and other evil
deeds; and then, the mass and the sermon are listened to without
edification, the prayer is spoken without faith. It almost
happens that men think it is sufficient that we look on at the
mass with our eyes, hear the preaching with our ears, and say the
prayers with our mouths. It is all so formal and superficial! We
do not think that we might receive something out of the mass into
our hearts, learn and remember something out of the preaching,
seek, desire and expect something in our prayer. Although in this
matter the bishops and priests, or they to whom the work of
preaching is entrusted, are most at fault, because they do not
preach the Gospel, and do not teach the people how they ought to
look on at mass, hear preaching and pray. Therefore, we will
briefly explain these three works.
