On his way to that first service, rowing from Rockledge to the courthouse, he had been struck by the beauty of the scenery, and had recalled a passage from the Epistle of James: "Every good and perfect gift comes down from above, from the Father of Lights."
The legend goes that he asked for the congregation to be named after the passage's author, St. James.
This first meeting of the organized congregation was reenacted in 2005, in a 150th anniversary celebration, during which Charles Tuttle III portrayed his great-grandfather Isaac's arrival at the courthouse by rowboat.
According to church archives, a variety of furnishings in the church reflect the rich history of the building.
The altar was built at the old county work farm, which is now the Great Meadow State Prison in Comstock.
The organ was manufactured by Ernest M. Skinner & Co., the masterful firm that built the finest instruments of its day, including the organ at St. John the Divine Cathedral in Manhattan. St. James' Skinner organ is one of the four smallest Skinner organs ever built, according to church records.
The cross over the altar was designed and carved by Bob Voyeau, and was given in member of the grandson of the Rev. Isaac Tuttle, Charles Tuttle II.
