"As a good man, with his reputation for piety, for evangelism and for his sufferings for the truth, Baxter’s errors had much more influence than those of lesser men. It was chiefly Baxter’s thinking which led to the split between Presbyterians and Independents in the 1690s and it is generally accepted that Baxter’s disciples among the Presbyterians set the course which finished up with almost that whole tradition becoming Unitarian. Referring to English Presbyterianism, Samuel J. Baird writes; ‘Beginning in the theological aberrations of the sainted Baxter, it ended in blasphemies against the Son and Spirit of God’. The seeds sown in Baxter’s lifetime did not stop with the English Presbyterians. What he wrote on justification and against imputed righteousness was in part reprinted by John Wesley and had widespread influence on the course of Methodism on both sides of the Atlantic. Presbyterianism in Scotland was also widely affected. Baxter’s example taught a generation of Scots ministers to regard the orthodox doctrine of justification as Antinomian and, as John Macleod comments, this ‘developed the legal strain which at a later stage showed itself as full-blown Moderatism’."
