Rahman converted to Christianity 16 years ago when he fled to Pakistan to escape fighting in his native Afghanistan. He was released from a Kabul prison overnight after tests to determine his mental stability.
But Adams says the Afghan court failed to announce a clear precedent that protects the religious freedom of all Afghan citizens -- regardless of whether they believe in Islam or another faith.
"There are reports that there are thousands of Christians in Afghanistan -- all of whom are afraid of the death penalty for apostasy and have to go about their religious observance in secret," Adams told RFE/RL. "It's no different than it used to be in the Soviet Union -- or in some parts of China now or North Korea."
Adams says freedom of religion does not exist in a country that threatens its citizens with death if their faith differs from the state-sanctioned religion.
