De Maistre was baptised into the Catholic Church while living in London in 1949. His biographer, Heather Johnson, has speculated that the devastating experiences of the Second World War may have led to the artist's conversion and to his exploration of religious themes in his art. De Maistre's religious works were received with considerable interest, due to his synthesis of a modernist style with traditional, religious subject matter. In 1954 de Maistre was commissioned to paint a series of Stations of the Cross for the Great Corridor which connects Westminster Cathedral with its Clergy House. The small, portable format of this work is derived from the European iconic tradition, which were used for personal devotions by travellers.
