It is (as it is phrased in the Decalogue, and elsewhere in Holy Scripture) an assuming the name of God, and applying it to our purpose; to countenance and confirm what we say. It is an invocation of God as a most faithful Witness, concerning the truth of our words, or the sincerity of our meaning. It is an appeal to God as a most upright Judge whether we do prevaricate in asserting what we do not believe true, or in promising what we are not firmly resolved to perform. It is a formal engagement of God to be the Avenger of our trespassing in violation of truth or faith. It is a binding our souls with a most strict and solemn obligation, to answer before God, and to undergo the issue of His judgment about what we affirm or undertake. Such an oath is represented to us in Holy Scripture. Whence we may collect, that swearing doth require great modesty and composedness of spirit, very serious consideration and solicitous care, that we be not rude and saucy with God, in taking up His name, and prostituting it to vile or mean uses; that we do not abuse or debase His authority, by citing it to aver falsehoods or impertinences; that we do not slight His venerable justice, by rashly provoking it against us; that we do not precipitately throw our souls into most dangerous snares and intricacies. For let us reflect and consider: What a presumption is it without due regard and reverence to lay hold on God's name; with unhallowed breath to vent and toss that great and glorious, that most holy, that reverend, that fearful and terrible name of the Lord our God, the great Creator, the mighty Sovereign, the dreadful Judge of all the world; that name which all heaven with profoundest submission doth adore, which the angelical powers, the brightest and purest Seraphim, without hiding their faces, and reverential horror, cannot utter or hear; the very thought whereof should strike awe through our hearts, the mention whereof would make any sober man to tremble? [Greek], "For how," saith St. Chrysostom, "is it not absurd that a servant should not dare to call his master by name, or bluntly and ordinarily to mention him, yet that we slightly and contemptuously should in our mouth toss about the Lord of angels? "How is it not absurd, if we have a garment better than the rest, that we forbear to use it continually, but in the most slight and common way do wear the name of God?" How grievous indecency is it, at every turn to summon our Maker, and call down Almighty God from heaven, to attend our leisure, to vouch our idle prattle, to second our giddy passions, to concern His truth, His justice, His power in our trivial affairs!
