Bishop Nolan said: "Father George Thompson was a man whose life was inspired and motivated by a deep faith in Jesus Christ. A faith he put into practice by embracing three vocations: teaching, politics and the priesthood. In each of these he sought to serve God and to serve others. We give thanks to God for all the good that he did throughout his life."
Bishop Nolan added: "The people of Galloway have been blessed by his commitment to public service, but as Bishop of Galloway I am particularly grateful to him for his years of service as a priest. We commend Fr. George Thompson in our prayers to the loving mercy of God. May he rest in peace."
