The Christian footprint in Australian society and culture remains broad, particularly in areas of social welfare and education provision and in the marking of festivals such as Easter and Christmas. Though the Australian Constitution of 1901 protects freedom of religion and separation of church and state, the Church of England held legal privileges in the early colonial period, when Catholicism in particular was suppressed, and sectarianism was a feature of Australian politics well into the 20th century, as was collaboration by Church and State in seeking the conversion of the indigenous population to Christianity. Today, the Catholic Church is second only to government as a provider of social services, through organisations such as Catholic Social Services Australia and the St Vincent De Paul Society. The Anglican Church's Anglicare network is similarly engaged in areas such as emergency relief, aged care, family support service and help for the homeless. Other denominations assist through networks like UnitingCare Australia and the Salvation Army, and around a quarter of students attend church owned schools.
