Catholic Social Teaching is just Catholic moral teaching with emphasis upon the political and economic realms. This premise is in tension to the way many envisage the Church’s moral teaching, separating – even to the point of opposing – the Church’s commitment to “social justice” and its teachings on matters of life and sex. After a brief elaboration of the nature and purposes of CST and its dominant “principles,” the chapter reflects on why the disassociation between CST and Catholic moral teaching has come about. It argues that as a body of ethical instruction CST would be much more coherent and pastorally effective by explicitly incorporating the exceptionless moral norms taught and defended by the Church. The final section contains suggestions on how this incorporation might take place.
