An interesting instance of liberalizing orthodoxy is furnished by the Rev. Arthur Ashley Sykes, who contributed many volumes to the general deistic discussion, some of them anonymously. In the preface to his Essay on the Truth of the Christian Religion (1732; 2nd ed. enlarged, 1755) Sykes remarks that "since ... systematical opinions have been received and embraced in such a manner that it has not been safe to contradict them, the burden of vindicating Christianity has been very much increased. Its friends have been much embarrassed through fear of speaking against local truths; and its adversaries have so successfully attacked those weaknesses that Christianity itself has been deemed indefensible, when in reality the follies of Christians alone have been so." Were Christians left to the simple doctrines of Christ and the Apostles, he contends, Infidelity could make no converts. And at the close of the book he writes: "Would to God that Christians would be content with the plainness and simplicity of the gospel.... That they would not vend under the name of evangelical truth the absurd and contradictory schemes of ignorant or wicked men! That they would part with that load of rubbish which makes thinking men almost sink under the weight, and gives too great a handle for Infidelity!" Such writing could not give satisfaction to the ecclesiastical authorities; and as little could Sykes's remarkable admission (The Principles and Connection of Natural and Revealed Religion, 1740, p. 242): "When the advantages of revelation are to be specified, I cannot conceive that it should be maintained as necessary to fix a rule of morality. For what one principle of morality is there which the heathen moralists had not asserted or maintained? Before ever any revelation is offered to mankind they are supposed to be so well acquainted with moral truths as from them to judge of the truth of the revelation itself." Again he writes:-- "Nor can revelation be necessary to ascertain religion. For religion consisting in nothing but doing our duties from a sense of the being of God, revelation is not necessary to this end, unless it be said that we cannot know that there is a God, and what our duties are, without it. Reason will teach us that there is a God ... that we are to be just and charitable to our neighbours; that we are to be temperate and sober in ourselves" (id. p. 244).
