Thomas Baldwin (1753–1825) was one of the most prominent Baptist clergymen in early America. He served as pastor of the Second Baptist Church in Boston from 1790 until his death in 1825, and was widely regarded as faithful, affectionate, devoted, and very successful in his ministry. He was also deeply engaged in civic life — before entering the ministry he served New Hampshire as a legislator, and after moving to Boston he was frequently elected chaplain to the General Court of Massachusetts and served as a member of the Massachusetts Constitutional Convention of 1821. He held trusteeships at Brown University, Waterville College, and Columbian College, and in 1803 he commenced publication of the American Baptist Magazine, of which he was first sole, and then senior editor until his death.

The substance of the catechism was first read before the Boston Baptist Association at their annual meeting on September 21, 1815, and was copyrighted in 1816. A committee of that Association endorsed it as preferable to any other catechism they had seen, and cheerfully recommended it to all persons responsible for educating children.

This denominational endorsement is significant — it gave the work an official standing within New England Baptist life. It was published by Lincoln & Edmands in Boston and sold at the very low price of 6 cents per copy, 60 cents per dozen, or $4.50 per hundred Bowdoin, indicating it was designed for mass distribution and widespread religious instruction.

By 1826 — just a year after Baldwin's death — the catechism had already passed through six editions, a remarkable measure of its popularity and utility in the early American Baptist community.

The work sits at an important intersection of American religious and educational history. In the early nineteenth century, catechisms were a primary vehicle for instructing children and new converts in core doctrinal and moral principles. That the leading Baptist association of New England chose Baldwin's text as its preferred instrument for this purpose reflects both his theological authority and the institutional role the work played in shaping Baptist identity during a formative period of American denominational life. For scholars of early American religion, it is a primary source document for understanding Baptist doctrine, pedagogy, and publishing in the young republic.

Though widely distributed, inexplicably scarce, there being but one other, and that a later edition, available.
