Catholics and the Orthodox see the primary repository of divine revelation (in the sense which Protestants call "special revelation", i.e., as distinguished from the revelation embodied in nature) as the Church. The inerrant and inspired Scriptures are the written tradition of the Church (the Church is the New Israel, so this includes the Old Testament), but the Church also expresses divine revelation in liturgy, oral tradition, the Councils and the Magisterium.[note 1] Protestants, on the other hand, tend to find divine revelation primarily in Scripture, though there are some Protestants who think that the Church is the primary respository of revelation, but that this revelation is only found infallibly in the Church's Scriptures.
It is often argued that seeing the Church as primary here makes much sense in light of the fact that the canon of Scripture is defined by the Church.
Here I want to suggest a different argument. The primary object of our faithful trust is Jesus Christ. But the Church is the mystical body of Christ. In trusting the Church, we are trusting Christ. Seeing revelation as embodied primarily in the Church fits well with the christological focus of our faith. While, of course, the Holy Spirit who inspires the Scriptures is perfectly trustworthy, New Testament faith is primarily a trust in Jesus Christ. Trust is an interpersonal relation, so it makes sense to distinguish the persons of the Trinity in respect of it. Seeing the Church, the mystical body of Christ, united as such by the Holy Spirit, as the primary respository of revelation fits particularly well with the christological nature of our Christian faith.
