After making an extensive study of the Latin language, he felt a desire to study Greek that he might read the New Testament in the original, but he had no means to prosecute this study. While in doubt as to how he could attain so desirable an end the Reverend William Bradford, of Wintonbury, a small parish composed, as its name imports, of a part of three towns, Winsor, Farmington and Symsbury, offered to instruct him in the Greek language. This benefactor promised also to secure there for Mr. Haynes a school paying him sufficient money to defray his expenses. Mr. Haynes said: "I exerted myself to the utmost to instruct the children of my school, and found I gave general satisfaction. The proficiency I made in studying the Greek language I found greatly exceeded the expectations of my preceptor."[6] He was thus serving as a "spiritual teacher in a respectable and enlightened congregation in New England, where he had been known from infancy only as a servant boy, and under all the disabilities of his humble extraction." "That reverence which it was the custom of the age to accord to ministers of the gospel," says his biographer, "was cheerfully rendered to Mr. Haynes."[7] All classes and ages were delighted with the sweet, animated eloquence of the man. In consideration of his talents Middlebury College later conferred upon him the degree of master of arts.[8] This led friends to advise that he should be licensed to preach, and on November 29, 1780, after "an examination in the languages, sciences, doctrines and experimental religion," he was licensed and preached intelligently from Psalm 96:1. He was ordained soon thereafter. Then came an early call to begin his ministry at the Congregational meeting house at Middle Granville, where he labored five years, preaching eloquently with zeal. The time was one of moral darkness with intemperance, profanity and infidelity rife. Strange doctrines intruded. Vice came boldly forward, but, like a rock, the young minister stood by his Lord and faith. Among the pious in the church was Bessie Babbitt. She was a woman of considerable education and was engaged as a teacher in her town. Looking to Heaven for guidance, she was led, with consistent delicacy, to offer her heart to her pastor. He commended the proposal to God in prayer, and consulted other ministers. Knowing his birth and race, he sought their counsel. They advised in favor, and on September 22, 1773, they were married. There began then their happy married life which was blessed with nine children.[9]
