Our lot is cast in an age of abounding unbelief, scepticism, and, I fear I must add, infidelity. Never, perhaps, since the days of Celsus, Porphyry, and Julian, was the truth of revealed religion so openly and unblushingly assailed, and never was the assault so speciously and plausibly conducted. The words which Bishop Butler wrote in 1736 are curiously applicable to our own days:—“It is come to be taken for granted by many persons, that Christianity is not even a subject of inquiry; but that it is now at length discovered to be fictitious. And accordingly they treat it as if, in the present age, this was an agreed point among all people of discernment, and nothing remained but to set it up as a principal subject of mirth and ridicule, as it were by way of reprisals for its having so long interrupted the pleasures of the world.” (Butter’s Analogy, Introduction.) I often wonder what the good Bishop would have now said, if he had lived in the present day.

In reviews, magazines, newspapers, lectures, essays, and sometimes even in sermons, scores of clever writers are incessantly waging war against the very foundations of Christianity. Reason, science, geology, anthropology, modern discoveries, free thought, are all boldly asserted to be on their side. No educated person, we are constantly told nowadays, can really believe supernatural religion, or the plenary inspiration of the Bible, or the possibility of miracles. Such ancient doctrines as the Trinity, the deity of Christ, the personality of the Holy Spirit, the atonement…the necessity and efficacy of prayer, the existence of the devil, and the reality of future punishment, are quietly put on the shelf as useless old Almanacs, or contemptuously thrown overboard as lumber! And all this is done so cleverly, and with such an appearance of candour and liberality, and with such compliments to the capacity and nobility of human nature, that multitudes of unstable Christians are carried away as by a flood, and become partially unsettled, if they do not make complete shipwreck of faith. . .

. . .The times require at our hands distinct and decided views of Christian doctrine.

I cannot withhold my conviction that the professing Church of the nineteenth century is as much damaged by laxity and indistinctness about matters of doctrine within, as it is by sceptics and unbelievers without. Myriads of professing Christians nowadays seem utterly unable to distinguish things that differ. Like people afflicted with colour-blindness, they are incapable of discerning what is true and what is false, what is sound and what is unsound. If a preacher of religion is only clever and eloquent and earnest, they appear to think he is all right, however strange and heterogeneous his sermons may be. They are destitute of spiritual sense, apparently, and cannot detect error. Popery or Protestantism, an atonement or no atonement, a personal Holy Ghost or no Holy Ghost, future punishment or no future punishment, High Church or Low Church or Broad Church, Trinitarianism, Arianism, or Unitarianism, nothing comes amiss to them: they can swallow it all, if they cannot digest it! Carried away by a fancied liberality and charity, they seem to think everybody is right and nobody is wrong, every clergyman is sound and none are unsound, everybody is going to be saved and nobody going to be lost. Their religion is made up of negatives; and the only positive thing about them is that they dislike distinctness and think all extreme and decided and positive views are very naughty and very wrong!

These people live in a kind of mist or fog. They see nothing clearly, and do not know what they believe. They have not made up their minds about any great point in the Gospel, and seem content to be honorary members of all schools of thought. For their lives they could not tell you what they think is truth about justification, or regeneration, or sanctification, or the Lord’s Supper, or baptism, or faith, or conversion, or inspiration, or the future state. They are eaten up with a morbid dread of controversy and an ignorant dislike of party spirit; and yet they really cannot define what they mean by these phrases. The only point you can make out is that they admire earnestness and cleverness and charity, and cannot believe that any clever, earnest, charitable man can ever be in the wrong! And so they live on undecided; and too often undecided they drift down to the grave, without comfort in their religion, and, I am afraid, often without hope. . .

. . .Mark what I say. If you want to do good in these times, you must throw aside indecision, and take up a distinct, sharply-cut, doctrinal religion. If you believe little, those to whom you try to do good will believe nothing. The victories of Christianity, wherever they have been won, have been won by distinct doctrinal theology; by telling men roundly of Christ’s vicarious death and sacrifice; by showing them Christ’s substitution on the cross, and His precious blood; by teaching them justification by faith, and bidding them believe on a crucified Saviour; by preaching ruin by sin, redemption by Christ, regeneration by the Spirit; by lifting up the brazen serpent; by telling men to look and live—to believe, repent, and be converted.

This—this is the only teaching which for eighteen centuries God has honoured with success, and is honouring at the present day both at home and abroad. Let the clever advocates of a broad and undogmatic theology—the preachers of the Gospel of earnestness, and sincerity and cold morality—let them, I say, show us at this day any English village or parish, or city, or town, or district, which has been evangelized without “dogma,” by their principles. They cannot do it, and they never will. Christianity without distinct doctrine is a powerless thing. It may be beautiful to some minds, but it is childless and barren. There is no getting over facts. The good that is done in the earth may be comparatively small. Evil may abound, and ignorant impatience may murmur and cry out that Christianity has failed. But, depend on it, if we want to “do good” and shake the world, we must fight with the old apostolic weapons, and stick to “dogma.” No dogma, no fruits! No positive Evangelical doctrine, no evangelization! [emphases added]
