Fr Pantin's Episcopal consecration took place on March 19, 1968-the day he was ordained as T&T's first local Archbishop. As Archbishop he took the motto: "All things to all men" which would today be translated: "All things to all people." During Pantin's 32 years as Archbishop, he made strenuous efforts to fulfil the expectations of that motto. Fr Pantin wished for people's betterment and he created the Mary Care Centre-a home for pregnant, unmarried teenagers. In his sermons, he usually called attention to the lot of the homeless and the lonely. He was also instrumental in forming the Inter-Religious Organisation and took an active role in that group.
