Calvary Methodist Episcopal Church was erected on a piece of land conveyed to the trustees on the 15th day of September 1821, by Richard Webster, Sr., and Phoebe, his wife, and Richard Webster, Jr., and his wife. The sum paid was 5 shillings (or about $1.00 current money).

The church was founded by Richard Webster, Sr., and most of the construction was done by his sons, with the help of others. Mr. Everist presented the first Bible. He may have been the first appointed minister or a devout layman. Samuel Dever was the smith who made the nails. His shop stood nearby on the northernmost field.

Mr. Paul Andrews and Nicholas Allender were the stone masons, and the carpenter was Mr. Spear. Mr. George V. Dever and Mr. James Webster carried stone to the masons. Mrs. Rachel Webster prepared and carried on her head in a corn basket the mid-day meal for the workmen.

Calvary has had a number of affiliations, all within the Methodist fold. From 1821 to 1843 it was evidently a station, part of the Harford Circuit which comprised about 30 congregations. In 1844 it became part of the East Harford Circuit of the Baltimore Conference, along with Garrison Chapel, Abingdon Chapel, Smith's Chapel, Rock Run, Bush Chapel and Gunpowder Chapel. For many years Calvary was part of a three-point charge with Abingdon Chapel (now Cokesbury Memorial) and Smith's Chapel, and now shares the two-point Abingdon Charge of the Baltimore-Harford District with Cokesbury Memorial United Methodist Church.
