Horatius Bonar, quoted in "Christ is All": The Piety of Horatius Bonar, ed. Michael A. G. Haykin and Darrin R. Brooker (2007), 31-3:
Some well-meaning theological literateurs, or rather amateur theologians, who patronize religion in their own way, are fain to warn us of the danger of not "keeping abreast of the age," as if we were imperilling Christianity by not being quite so learned in modern speculations as they are. We should like, certainly, to "keep abreast" of all that is true and good, either in this age or any other; but as to doing more than that, or singling out this age as being pre-eminently worthy of being kept abreast of, we hesitate.
To be "up to" all the errors, fallacies, speculations, fancies, mis-criticisms of the age, would be an achievement of no mean kind; and to require us to be "up to" all this under threat of endangering Christianity, or betraying the Bible, is an exaction which could only be made by men who think that religion is much beholden to them for their condescending patronage; and will be accepted by men who are timid about the stability of the cross of Christ if left unpropped by human wisdom; and who, besides, happen to have three or four lifetimes to spare. We may be in a condition for believing, and even defending the Bible, without have mastered the whole deistical literature of the last century or the present...
In attempting to "keep abreast of the age," there is some danger of falling short of other ages; and we are not sure but that the object of those who shake this phrase so complacently in our faces, both as a taunt and a threat, is to draw us off from the past altogether, as if the greater bulk of its literature were rude lumber, a mere drag upon progress...Old theological terms and Scripture phraseology are set aside, or spoken in an undertone, or used in a loose sense. Sharp adhesion to old doctrines is imbecility; and yet defined expression of the new is avoided, the mind of the age being in a transition state, unable to bear the whole of what the exact and honest exhibition of "advanced" Christianity would require to utter.
Many of our young men are more afraid of being reckoned Calvinistic than Platonic; they shrink from bold and definite statements of Reformation doctrine, lest they should be pronounced "not abreast of the age"--stereotyped, if not imbecile. Indefinite language, mystical utterances, negative or defective statements, which will save the speaker's or writer's orthodoxy without compromising his reputation for "intellect" and "liberality"--these are becoming common. Manya re doing their best to serve to masters, to preach two gospels, to subscribe two confessions of faith, to worship two Gods, to combine to religions, to grasp two worlds; they would fain be neither very evangelical nor very heretical.
