In the summer of 1980, Benjamin F. Long was painting "The Last Supper" with approximately 20 young artists which he invited to study with him and to learn the art of the frescoes.

Local people served as models for all the biblical figures except the waiting maid, Judas, Thomas, and Christ. Benjamin F. Long was the model for Thomas.

This fresco was dedicated to the greater glory of God by Bishop William Weinhauer of the Diocese of Western North Carolina on August 30, 1980. In a scrip at the right of the foot-washing bowl, Benjamin F. Long painted a dedication to his father, who died just as the fresco was being completed.

Across the street from the church is the Mission House where most of the priests stay during their service. Also in the mission house is a gift shop for tourists.
