It’s good that the World Council of Churches wrote a letter to Castro regretting a “miscarriage of justice” in a trial of Cuban dissidents. It’s less good that they made a point of saying that their letter was “both friendly and firm in tone.” And the substance of their argument was genuinely bad: authorities should “not allow their decisions to jeopardise the integrity of the Cuban revolution” even though “Cuba has recently experienced an increase in external pressures and interference in its sovereignty and independence, especially by the government of the United States of America.” What conceivable grounds could a Christian have for concern about the integrity of the Cuban revolution?
