"Interview: SSPX's Fellay Speaks on Meeting with Cardinal Müller - Kasper's consistently following Spirit of the Council to its logical end" (RC, October 3, 2014). Two excerpts. The first on relations with Rome:
There is a new pope and a new prefect heading the Congregation for the Doctrine of the Faith. And this recent interview shows that neither they nor we want a break in our relations: both parties insist that it is necessary to clarify the doctrinal questions before there is any canonical recognition. This is why, for their part, the Roman authorities are demanding the endorsement of the Doctrinal Preamble which, for our part, we cannot sign because of its ambiguities.The second on Kasper:
Cardinal Kasper is quite logical and perfectly consistent: he proposes applying pastorally to marriage the new principles concerning the Church that were spelled out at the Council in the name of ecumenism: there are elements of ecclesiality outside the Church. He moves logically from ecclesial ecumenism to matrimonial ecumenism. Thus, in his opinion, there are elements of Christian marriage outside of the sacrament.
