The Third Commandment:  “You shall sanctify the holy Day.”

“Note, then, the power and force of this commandment consist not of the resting but of the sanctifying, so that this day should have its own particular holy work.  Other trades and occupations are not properly called holy work unless the doer himself is made holy.  But here a work must be performed by which the doer himself is made holy; this, as we have heard, takes place only through God’s Word.”

The Second Commandment:  “You shall not take the name of God in vain.”

“For to lie and deceive is in itself a gross sin, but it is greatly aggravated when we attempt to justify and confirm it by invoking God’s name and using it to cover our shame.  So from a single sin a double one results – indeed, manifold lies.”

The First Commandment:  “You shall have no other gods before me.”

“To have a god is nothing else than to trust and believe him with our whole heart….To have God, you see, does not mean to lay hands upon him, or put him into a purse, or shut him up in a chest.  We lay hold of him when our heart embraces him and clings to him.  To cling to him with all our heart is nothing else than to entrust ourselves to him completely.”
