Cardinal Walter Kasper, the President of the Pontifical Council for  Promoting Christian Unity, has provided an irenic exegesis of the recent CDF Declaration that has been commented on in a post below.

Kasper writes:

A first and quick reaction among Protestant Christians to the declaration of the Congregation of the Doctrine of Faith Responses to Some Questions Regarding Certain Aspects of the Doctrine on the Church has been one of irritation.

Therefore, no new situation has developed. Nor is there any objective reason for outrage, or the feeling of being offended. Every dialogue presupposes clarity about the different positions. Our Protestant partners are the ones who have recently spoken about an ecumenism of profiles. If this declaration now explains the Catholic profile and expresses what, in a Catholic view, unfortunately still divides us, this does not hinder dialogue, but promotes it.
