Moravianism was more than ever a _vexata quæstio_. Whitefield, in a letter dated March 30, 1751, remarks:—“I doubt not but there are many holy souls among the Moravians; but their not preaching the law, either as a _schoolmaster_ to show us our need of Christ, or as a _rule of life_, after we have closed with Him, is what I can in nowise concur with. These their two grand mistakes, together with their unscriptural expressions in their hymns, and several superstitious fopperies lately intruded among them, make me think they are sadly departed from the simplicity of the gospel.”[108] A friend, writing to Wesley, at the commencement of the year, observes:— “No doubt God had wise ends in permitting the _Unitas Fratrum_ to appear, just as the people of God began to unite together; but we cannot fathom His designs. Very probably we should have been now a very different people from what we are, had we had only our own countrymen to cope with. We should then have set the plain gospel of Christ against what is palpably another gospel. But this subtle poison has more or less infected almost all among us. We would put gospel heads on bodies ready to indulge unholy tempers. Although as a society we stand as clear of joining with the Beast as any other, yet we have not purged out all his leaven; the antinomian leaven is not yet cast out. All our preaching at first was pointed at the heart; and in almost all our private conversation, ‘Do you feel the love of God in your heart? Does His Spirit reign there? Do you walk in the Spirit? Is that mind in you which was in Christ?’ were frequent questions among us. But while these preachers to the heart were going on gloriously in the work of Christ, the false apostles stepped in, laughed at all heart work, and laughed many of us out of our spiritual senses; for, according to them, we were neither to see, hear, feel, nor taste the powers of the world to come, but to rest contented with what was done for us seventeen hundred years ago. ‘The dear Lamb,’ said they, ‘has done all for us; we have nothing to do, but to believe.’ Here was a stroke at the whole work of God in the heart! And ever since, this German spirit has wrought among us, and caused many to rest in a barren, notional faith, void of that inward power of God unto salvation.”
