Regarding the article "On Brazil's Front Line, Priest Says Liberation Theology Is Still Basic to Helping the Poor," Oct. 11: The ecclesiastical base communities are not, as the author asserts, "neighborhoods organized around leftist political beliefs." These are faith-based communities where people gather around the Word, reading the Gospel in light of their daily lives and reading social reality in light of the Gospel.This cross-fertilization of faith in a God of life and the lived reality of misery and oppression leads these communities to take up action on behalf of life: literacy programs, community day care, union organizing, and supporting local political parties.
