John Walker, in addition to having convictions against the carrying of arms by Christians and the sinfulness of taking oaths, held a disdain for the joining together of Church and State under the rule of the Roman Emperor Constantine. Walker, like Glas and Sandeman, rejected the fusion of Church and State, and had no use for the intervention of government into the church, or the church into the government. In a longer essay on religious establishments made by human governments, Walker not only bemoaned this fusion, but he also took a potshot at English King James VI, who not only oppressed Walker’s own people (and who, through the Union of the Crowns, was declared King of both England and Ireland), but who famously declared that without bishops, there could be no King: a clear rejection of both Presbyterianism (which the Glasites originated from), and Congregationalism (the Glasite polity).
The writings of the earliest fathers (as they are called) of the Church prove, what a rapid progress this defection made after the death of the Apostles. But it was not till the Roman empire ceased to be professedly heath, and Constantine assumed the name of Christian, that its malignity became fully developed ; and that connection took place between Church and State, which completely secularized the kingdom of Jesus Christ. Then indeed the flood of corruption rapidly swept before it almost every vestige of scriptural Christianity. Then the sword of human power was considered as the great means of promoting their satanic religion. Then appeared the awful spectacle of different factions, under the name of Christian, employing that sword against each other, as they successively climbed to political greatness on the stepping-stone of their several systems. Then were introduced into the house of God the civil pains and penalties of exile, fines, imprisonment, and death ; with the worldly prizes of riches and honor, and political advancement, to tempt the ambition of carnal religionists. Then advanced with hasty strides the assumptions of priestly authority and hierarchical dominion, originating that stupid and wicked cry of—NO BISHOP, NO KING—which continued current to the present day ; till at length what they called the Altar overtopped the Throne, and the popes of Rome, under the blasphemous claim of deriving their authority by lineal succession from the Apostle Peter, and acting as the Viceregents of Christ,—were enabled to establish themselves in universal sovereignty over the very monarchs who had aided their rise, and conferred kingdoms or deposed kings at pleasure ; while Christendom was overspread with a uniformity of idolatrous superstition and impious mummery, presented to the besotted nations as the religion of Jesus Christ….
In many instances the kings of the earth, who had groaned under the yoke of the Roman pontiff, were glad to patronize the Reformation, as opposed to that domineering power. And alas ! the reformers generally fell into the snare of their patronage ; and in order to avail themselves of the protection and aids of human power, abandoned the principle that Christ’s kingdom is not of this world ; continued that coalition between Church and State, which is essentially inconsistent with scriptural Christianity; and this proved their new Churches to be the genuine progeny of that great whore, with whom the kings of the earth have committed fornication, and who is described as the Mother of harlots and abominations of the earth (Rev. xvii. 5.) Hence, in Churches bearing the name of Christian and of Protestant, the awful spectacle was still exhibited of temporal pains and penalties introduced to enforce obedience to their mandates ; acts of human legislature establishing their religious creeds, and ordering their religious observances ; with several carnal inducement held out to allure conformity, and all the worldly aids of pageantry and pomp to excite superstitious reverence.
To this State-religion the continued existence of the race of Clergy was essential. And accordingly they continued,—a class of pretended agents between God and the people, tricked out int he trappings and claims of the Jewish priesthood ;—of that priesthood which had its termination and absolute abolition in Him, who is the great High Priest over the House of God, on the completion of whose work the shadows which had prefigured him passed away… A man appointed by worldly rulers to what is called the episcopal function, after some ceremonies have been gone through with him by others similarly appointed, is supposed to be transformed into a—successor to the Apostles in the government of the Church of Christ !
