He was 86:

The Rev. Robert F. Drinan, a Jesuit who served in Congress for 10 years until stepping down in response to a papal order, died Sunday. He was 86 and lived here in housing for the Georgetown University Jesuit community.

A university statement Sunday night said Father Drinan had recently been ill with pneumonia and congestive heart failure.

An internationally known human rights advocate, Father Drinan represented Massachusetts in the House of Representatives for 10 years in the 1970s, stepping down only after a worldwide directive from Pope John Paul II barring priests from holding public office.
