27 This is not the place to examine all our traducers, who they are, or whence they are, what is their power, what their knowledge, why they tremble at the mention of Christ, why they regard his disciples as enemies and as hateful persons; but with regard to ourselves to state expressly to those who will exercise common reason, in terms applicable to all of us alike—We Christians are nothing else than worshippers of the Supreme King and Head, under our Master, Christ.
If you examine carefully, you will find that nothing else is implied in that religion. This is the sum of all that we do; this is the proposed end and limit of sacred duties. Before Him we all prostrate ourselves, according to oar custom; Him we adore in joint prayers; from Him we beg things just and honourable, and worthy of His ear. Not that He needs our supplications, or loves to see the homage of so many thousands laid at His feet. This is our benefit, and has a regard to our advantage.
For since we are prone to err, and to yield to various lusts and appetites through the fault of our innate weakness, He allows Himself at all times to be comprehended in our thoughts, that while we entreat Him and strive to merit His bounties, we may receive a desire for purity, and may free ourselves from every stain by the removal of all our shortcomings.
