Overall, however, the poll of more than 12,000 Catholics in 12 countries reveals a church dramatically divided: Between the developing world in Africa and Asia, which hews closely to doctrine on these issues, and Western countries in Europe, North America and parts of Latin America, which strongly support practices that the church teaches are immoral.

The widespread disagreement with Catholic doctrine on abortion and contraception and the hemispheric chasm lay bare the challenge for Pope Francis’s year-old papacy and the unity it has engendered.

Among the findings:

●19 percent of Catholics in the European countries and 30 percent in the Latin American countries surveyed agree with church teaching that divorcees who remarry outside the church should not receive Communion, compared with 75 percent in the most Catholic African countries.
