MANILA — Philippine legislators passed a landmark bill Monday that would provide government funding for contraceptives and sexuality classes in schools despite strong opposition by the dominant Roman Catholic Church and its followers, some of whom threatened to ask the Supreme Court to block the legislation.

The Senate and the House of Representatives passed different versions of the bill, which languished in Congress for more than a decade as legislators avoided colliding with the influential church. The two versions will have to be reconciled before President Benigno Aquino III has an opportunity to sign the legislation.
