A. The chief purpose of theology is to provide an understanding of Revelation and the content of faith. The very heart of theological enquiry will thus be the contemplation of the mystery of the Triune God. The approach to this mystery begins with reflection upon the mystery of the Incarnation of the Son of God: his coming as man, his going to his Passion and Death, a mystery issuing into his glorious Resurrection and Ascension to the right hand of the Father, whence he would send the Spirit of truth to bring his Church to birth and give her growth. From this vantage-point, the prime commitment of theology is seen to be the understanding of God's kenosis, a grand and mysterious truth for the human mind, which finds it inconceivable that suffering and death can express a love which gives itself and seeks nothing in return. In this light, a careful analysis of texts emerges as a basic and urgent need: first the texts of Scripture, and then those which express the Church's living Tradition.
— Pope Bl. John Paul II, Fides et Ratio
B. Fides et Ratio gets a lot better starting around paragraph 80. Much of the rest is sort of redundant.
