Uncertain what to do next, Everett was encouraged by his pastor, Joseph Stevens Buckminster of the Brattle Street Church, to study for the ministry. This Everett did under the tutelage of Harvard President John Thornton Kirkland, earning his MA in 1813. During this time in particular he developed a facility for working with both the written and spoken word. The Reverend Buckminster died in 1812, and Everett was immediately offered the post at the Brattle Street Church on a probationary basis after his graduation, which was made permanent in November 1813. Everett dedicated himself to the work, and became a highly popular Unitarian preacher. Listeners wrote of his "florid and affluent fancy", and his "daring imagery", while one critic wrote what would become a Common criticism of his speaking style: "[Everett] spoke like some superior intelligence, discoursing to mortals of what they ought to feel and know, but as if [he] himself were too far exalted to require such feelings, and such knowledge himself." Everett, over the year he served in the pulpit, came to be disenchanted with the somewhat formulaic demands of the required oratory, and with the sometimes parochial constraints the congregation placed on him.
