Hi, I understand your fear here but I think you are mistaken on two levels: One, Cardinal Ratzinger does not argue that we need to enter into some collectivist anonymity. His emphasis throughout is on the personal relationship of the individual believer with the God who is personal. There is no space for anonymity in Cardinal Ratzingers understanding of faith, as is showin in his discussion of the God who manifests His power by being united with even the smallest and least powerful thing, in the Crib and on the Cross.
Secondly, when Cardinal Ratzinger speaks of the Ecclesial Form of Faith, what he speaks of is not any sort of eradication of the individual, but rather a group of persons who believe together. I would argue that this is consonant with both the Pauline and Johannine understanding of the Church: a group of people who believe in unity. Although there are Pauline passages about the individual assent of faith, these are balanced by the Pauline soteriology of the Body of Christ, and the 'New Man', who is not new men, but one whole, unified new man. If we believe things that are radically different or contradictory - a possibility which is implied in the notion of individual conscience being sovereign - then how can we be part of the same body, the same faith, (Eph 4).
Thirdly, I think the mentality of the individual being sovereign and salvation being an individual matter is itself rooted in an understanding which is 'traditional', that is handed on from one to another. the Evangelical understanding of salvation is just as much passed on by a community of conformnity as any other.
