The exercise of Social Covenanting with God, performed by his Church both in an Ecclesiastical and a National capacity, is a part of his service. Being a religious observance, this cannot be performed by the members of the Church collectively, whether united ecclesiastically or otherwise, if not associated as the Church of God. But also when, united both ecclesiastically and in a national capacity, they address themselves to it, they discharge an obligation incumbent upon them. The Lord Jesus is King of saints.[190] Ruled by his laws, these, not merely in their ecclesiastical, but also in their civil relations, do homage to him. Under two aspects in their social capacity they appear. _First_, in subjection to Him as King of Zion. United to Christ their spiritual Head, and to one another in him, they are members of one glorious body. And being members of his Church--which he has distinguished by the ministry of reconciliation, by his oracles, and by special ordinances, they are under Him, as its sole Head, and Lawgiver, and Governor, and King. As one community, in their faith, their worship, their discipline, their government, and communion, they are under his authority. Judges, and magistrates, and kings, having power in civil society, are recognised with divine approbation. But there is no human head of the Church. There are who rule therein; but over his house, He alone is Head and King. In civil life, there are who sway the sceptre among men. He, the King of kings, and Lord of lords, rules over these. But in his house there is none other than Himself, who is Lord or King. He is the head of the body, the Church: who is the beginning, the first-born from the dead; that in all things (or rather, _among all_) he might have the pre-eminence.[191] The apostles of our Lord were among those who, in the council held at Jerusalem several years after his ascension, acted as rulers in his Church by enacting a law which applied to the Christians at Antioch and elsewhere. And applicable to their conduct on such an occasion, and to that of all others exercising authority in the Church of God, were his words addressed to them before his death,--"Be ye not called Rabbi: for one is your Master, even Christ; and all ye are brethren. And call no man your father upon the earth: for one is your Father, which is in heaven. Neither be ye called masters: for one is your Master, even Christ."[192] The jurisdiction of the rulers in the Church is distinct from that of civil rulers. The powers of the former are spiritual, and with these powers the latter have no right to interfere. Each class of rulers have a sphere of their own; and only at their peril do those of the one class invade the authority of the other. By men the laws of a nation may be altered without being made contradictory to one another, or to oppose the law of God. But the laws of the Church were enacted by Christ himself. Suited to the
