simony: [13] Simony, a term which denotes the ‘selling of ecclesiastical offices’, perpetuates the name of Simon Magus. He was a Samaritan who according to Acts 8:18–20 tried to buy the power of conferring the Holy Ghost on people: ‘And when Simon saw that through laying on of the apostles’ hands the Holy Ghost was given, he offered them money, saying, Give me also this power, that on whomsoever I lay hands, he may receive the Holy Ghost. But Peter said unto him, Thy money perish with thee, because thou hast thought that the gift of God may be purchased with money’.
c. 1200, "the sin of buying or selling sacred things," from Old French simonie "selling of church offices" (12c.), from Late Latin simonia, from Simon Magus, the Samaritan magician who was rebuked by Peter when he tried to buy the power of conferring the Holy Spirit (Acts viii:18-20).
