Roman Catholic bishops in Tanzania have condemned as "unacceptable" a new science syllabus for primary schools that incorporates the teaching of proper condom use. "Introduction of the [teaching of] use of condoms in schools, apart from being sinful, is indeed justification and opening the door for immoral lifestyles," Cardinal Polycarp Pengo, the archbishop of Dar es Salaam, said on Monday (January 9) in a statement issued on behalf of Tanzania's Episcopal Conference.
