During the second half of the 19th century the rectors were Alexander McCaul (1799–1863, Rector 1850–63), who coined the term "Judaeo Christian" in a letter dated 17 October 1821, and his son Alexander Israel McCaul (1835–1899, curate 1859–63, rector 1863–99). Another son, Joseph Benjamin McCaul (1827–92) served as curate from 1851 to 1854. The Revd Alexander McCaul Sr was a Christian missionary to the Polish Jews, who (having declined an offer to become the first Anglican bishop in Jerusalem) was appointed professor of Hebrew and rabbinical literature at King's College, London in 1841. His daughter, Elizabeth Finn (1825–1921), a noted linguist, was the wife of James Finn, the British Consul in Jerusalem from 1846 to 1863. She founded a number of organizations including the Jerusalem Literary Society, which was the forerunner to the Palestine Exploration Fund, the Society for the Relief of Persecuted Jews (Syrian Colonization Fund) and the Distressed Gentlefolk Aid Association (now known as Elizabeth Finn Care). Both McCaul and his daughter worked closely with Lord Shaftesbury.
