"Fisher's name is associated with a catechism designed to explain the 'Shorter Catechism of the Westminster Assembly.' What is known as Fisher's 'Catechism' (2 parts, Glasgow, 1753, 1760) was in reality the result of contributions by many ministers of the body, which were made use of by three of the leading men, Ebenezer and Ralph Erskine and Fisher. Fisher survived the other two; and as the duty of giving a final form to the work, as well as executing his own share, devolved on him, it is usually spoken of as his. It is a work of great care, learning, and ability; it has passed through many editions; it was long the manual for catechetical instruction in the secession church; and it was a favourite with evangelical men outside the secession like Dr. Colquhoun of Leith and Robert Haldane. Fisher was the author of various other works, chiefly bearing on matters of controversy at the time, and illustrative of Erskine's work. Though not so attractive a preacher as the Erskines, nor so able an apologist as Wilson, yet by the weight of his character and his public position he exerted a very powerful influence on the secession, and contributed very materially to its progress and stability." - Wikipedia.
