Imam Khomeini, the late founder of the Islamic Republic recommended the Christian pope, clerics, priests and scholars to confront aggressive policies of colonial powers.
Parts of a historic speech of Imam Khomeini in this regard comes as following:
A criticism of the activities and position of the Christian clerics
It is the task of the Christian clerics to free Jesus Christ from the shackles that your presidents have bound him with and scrutinizing. Jesus Christ is closely watching the Christian scholars and clerics. He wants to see how you treat the aggressors who have subjected humanity to so much oppression. Have you ever brought up these crimes in your churches? Has the Pope ever condemned such cases of atrocities? Does the Pope, who has condemned our hostage taking, know the nature of these American detainees? Is the Pope, who considers himself a great Christian, authorized to condemn the acts of a deprived, poor nation like us? Has he ever condemned the atrocious acts of the kings, who pretend to be Christian within the last fifty years? Have the Christian clerics, as a whole, condemned the cruel acts, which have been imposed over us, and run counter to Christ’s instructions,. When I was in Paris, during the birthday of Jesus Christ, I wrote some articles depicting the crimes we have been exposed to, but the Pope did not let them get published. Why should a great Christian cleric treat the deprived nation in this way? Why should a great Christian cleric condemn the oppressed and side with the oppressors?
Are you not aware of the crimes having taken place here? Do you not know that a nation has been robbed of its reserves and now is miserable? Are you not familiar with the fact that a nation has been put under pressure for fifty years and its reserves have been plundered by the superpowers? Aren’t the Christian clerics aware that Carter has, in contrast to the saying and teachings of all prophets, frozen our assets in the foreign banks? We know that Jesus Christ (‘a) came to establish justice and it is your task to force the aggressors to stop engaging in cruelty. Are you not aware that a poor nation is under all sorts of pressures? Are you aware that by using sanctions Carter wants to let thirty-five million people die of hunger? Is the Pope aware of these facts and then he condemns us? Or, is he being given wrong information? If he is, then how deplorable our situation we that of Christianity, and the Christian scholars is! And if he is not, how deplorable the situation in the Vatican is! Why should you not relay to the Vatican what you have seen here? Does the Vatican refuse to listen to you? Does the Vatican listen to the proponents of the superpowers and to the oppressors, but refrain from listening to the oppressed? Where should we take our complaints against those superpower agents who pretend to be followers of Jesus Christ? Who should we discuss our problems with? Should we discuss them with you, Christian clerics? Should we complain to the Pope?
