56. In the second place, it is not enough that office and commandment be God-appointed. We his ministers should be conscious--and the people should so be taught--that efficacy of office is not of human effort, but is God's power and work. In other words, that which the office was designed to accomplish is not effective by virtue of our speech or action, but by virtue of God's commandment and appointment. He it is who orders; and himself will effectively operate through that office which is obedient to God's command. For instance, in baptism, the Lord's Supper and absolution, we are not to be concerned about the person administering the sacraments or pronouncing absolution--who he is, how righteous, how holy, how worthy. Worthiness or unworthiness of either administering or receiving hand effects nothing; all the virtue lies in God's command and ordinance. 57. This is the explanation of Peter's phrase, "the strength or ability which God supplieth." Effect is produced, not through man's power, not in obedience to man's will; but through the "strength" of God and because of his ordering. No man has a right presumptuously to boast his own power and ability effective, as the Pope does in his pretensions about keys and ecclesiastical power. Know that it is necessary to the efficacy of your office and the salutary character of your work or authority in the Church that God himself give and exert the influence. And that influence is exerted when, as before said, God's Word and testimony are present that the ministry in question is commanded, or authorized, of God. 58. Therefore it is earnestly enjoined that in the Church no attempt should be made by any individual to institute any order or perform any work, much or little, great or small, merely at the prompting of his own inclinations or in obedience to the advice of any man. Let him who would teach and work be sure that his words and acts are really of God--commanded by him. Until he is certain in this respect, let him abandon his office--suspend his ministry; let him engage in something else for a time. Nor should we hear or believe anything presented to us that does not bear indisputable evidence of being the divine Word, or command. For God will not permit mockery of himself in the things of his own prerogative and on which depends the salvation of souls; for souls will be led to eternal ruin where this rule and command are disregarded. "That in all things God may be glorified through Jesus Christ."
