Lossky is one of my favorite non-Lutheran theologians (he's Orthodox). He has a comment on Tradition that I've found remarkable for some time and thought I'd throw it out for anyone who wants to comment. It comes from his marvelous little essay "Tradition and Traditions" in *In the Image and Likeness of God* (SVS Press 1985). He writes:
"The pure notion of Tradition can then be defined by saying that it is the life of the Holy Spirit in the Church, communicating to each member of the Body of Christ the faculty of hearing, of receiving, of knowing the Truth in the Light that belongs to it, and not according to the natural light of human reason."
Now, am I just imagining things, or is there here perhaps a true kinship with the Explanation of the Third Article from the Small Catechism?
"I cannot by my own reason or strength believe in Jesus Christ, my Lord, or come to Him, but the Holy Spirit has called me by the Gospel, enlightened me with His gifts, sanctified and kept me in the true faith. In the same way, He calls, gathers, enlightens and sanctifies the whole Christian Church on earth and keeps it with Jesus Christ in the one true faith."
