During the first years of William Black's evangelistic labors, when several hundreds were converted and had joined the church, he was confronted with Antinomian teaching, through several visits from Henry Alline, who resided at Falmouth, Nova Scotia. Being called of God to preach in 1776, Alline itinerated through Nova Scotia, New Brunswick, and Prince Edward Island, preaching a strange mixture of doctrines, which unsettled the people in the churches, and many withdrew and formed the denomination of New Lights or Allinites, a body which had some influence until his death at Northampton in New Hampshire, United States, on February 2nd, 1784, when it gradually declined and was absorbed by other denominations, especially the Baptists. Alline published his peculiar views in a volume, entitled "Two mites on some of the most important and most disputed points of divinity cast into the treasury for the poor and needy, and committed to the perusal of the unprejudiced and impartial reader, by Henry Alline, servant of the Lord to His churches." A reply to this book was published in a volume by the Rev. Jonathan Scott, of Yarmouth, Nova Scotia, which contains copious extracts from it. Alline misrepresented all the leading doctrines of Christianity, assailing predestination and election, maintaining the freedom of man's will and upholding the final perseverance of the saints, emphasizing strongly conversion, and that the soul is at the same moment completely sanctified, while sin remains in the body; denying the resurrection of the body, and though sometimes practising water baptism, he denied its utility. He was a man of good address, eloquent of speech and of a lively disposition, and there was no doubt of his piety, as he was a good man, and these qualities made him a successful evangelist. His rank Antinomian doctrines caused havoc among the Presbyterian, Congregational and Methodist congregations in the places visited by him, and William Black mourned the withdrawal of two hundred persons in a little over a year from connection with the Methodist Church. It was very natural that the young evangelist should consult John Wesley on the matter, but the only help he received was a package of books, including two volumes of the writings of William Law, the great mystic, and instructions not to mention Alline's name in public, only to go on his way preaching the gospel. Though much depressed by the loss of so many members from the church, he had the satisfaction of seeing some return to the old fold, and toward Henry Alline himself he entertained respect. There remained no harshness, though the blow was heavy by the breach made in the congregations, as shown by a letter which he wrote to Alline when he was sick, in which, after speaking of the souls won for God, and his joy in Alline's success, he added, "Although we differ in sentiment, let us manifest our love to each other. I always admired your gifts and graces, and affectionately loved your person, although I could never receive your peculiar opinions. But shall we on this account destroy the work of God? God forbid! May the Lord take away all bigotry, and fill us with pure, genuine, catholic love!" That was charity indeed, but Henry Alline went on his way denouncing all who did not follow him.
