In Oasis of the West, Jones (1985: p118) contrasts religious affiliations in Strathfield between 1891 and 1947.

48 per cent of the Strathfield population were members of the Church of England, about 2 per cent more than the average for Sydney and 13.7 per cent were Roman Catholic, well below the 23.7 per cent average for Sydney; 8.2 per cent were Presbyterians, 8.3 per cent Methodists, both average for Sydney. Strathfield, however, was a haven for Congregationalists, who accounted for 13.2 per cent of those in Strathfield, far above the 4.2 per cent Sydney average.

Strathfield in 1947 was very much a centre for Protestants; 44 per cent of the population described themselves as Church of England and 23 per cent Congregationalists, Methodists, Presbyterians or Baptists. The 67 percent of Protestants greatly outnumbered the 20 per cent of Catholics.
