This interview has now been released in English over at Global Missiology, in their July 2014 issue. Here is his input regarding how the Vatican II document Nostra Aetate views Muslims:
8) The Catholic Church has come under a lot of fire from ex-Muslim Christians for its statement on Islam in the Vatican II document Nostra Aetate, which states that Muslims adore the one God, living and subsisting in himself and does not recommend evangelizing Muslims, but to work sincerely for mutual understanding and preservejustice and moral welfare (section 3). How do you read and interpret the statement of Nostra Aetate ?
We are treating here a crucial matter: Does Vatican II advise us to not evangelize Muslims? If this is the case, why risk death by becoming a Christian, if Islam is a way to salvation?
But this interpretation would mean that the Church recognises the segregation commanded by Muslim law between non-Muslims and Muslims, who are not allowed to be reached by the Good News. If this were the case, the Gospel would be null and void because it commands us to go and baptize all peoples.
