John William Fletcher (1729-1785) was a seminal theologian during the early methodist movement and the Church of England in the eighteenth century. Best known for the Checks to Antinomianism, he worked out a theology of history to defend the church against the encroachment of antinomianism as a polemic against hyper-Calvinism, whose system of divine fiat and finished salvation, Fletcher believed, did not take seriously enough either the activity of God in salvation history or an individual believer's personal progress in salvation. Fletcher made the doctrine of accommodation a unifying principle of his theological system and further developed the doctrine of divine accommodation into a theology of ministry. As God accommodated divine revelation to the frailties of human beings, ministers of the gospel must accommodate the gospel to their hearers in order to gain a hearing for the gospel without losing the goal of true Christianity. This book contains insights for pastors, missionaries, and Christian thinkers on true Christianity from Fletcher, who devoted himself, according to Wesley, to being "an altogether Christian."
