Dominus Iesus §8

8. The hypothesis of the inspired value of the sacred writings of other religions is also put forward. Certainly, it must be recognized that there are some elements in these texts which may be de facto instruments by which countless people throughout the centuries have been and still are able today to nourish and maintain their life-relationship with God. Thus, as noted above, the Second Vatican Council, in considering the customs, precepts, and teachings of the other religions, teaches that “although differing in many ways from her own teaching, these nevertheless often reflect a ray of that truth which enlightens all men”‌.²³

The Church's tradition, however, reserves the designation of inspired texts to the canonical books of the Old and New Testaments, since these are inspired by the Holy Spirit.²⁴ Taking up this tradition, the Dogmatic Constitution on Divine Revelation of the Second Vatican Council states: “For Holy Mother Church, relying on the faith of the apostolic age, accepts as sacred and canonical the books of the Old and New Testaments, whole and entire, with all their parts, on the grounds that, written under the inspiration of the Holy Spirit (cf. Jn 20:31; 2 Tim 3:16; 2 Pet 1:19-21; 3:15-16), they have God as their author, and have been handed on as such to the Church herself”‌.²⁵ These books “firmly, faithfully, and without error, teach that truth which God, for the sake of our salvation, wished to see confided to the Sacred Scriptures”‌.²⁶

Nevertheless, God, who desires to call all peoples to himself in Christ and to communicate to them the fullness of his revelation and love, “does not fail to make himself present in many ways, not only to individuals, but also to entire peoples through their spiritual riches, of which their religions are the main and essential expression even when they contain 'gaps, insufficiencies and errors'”‌.²⁷ Therefore, the sacred books of other religions, which in actual fact direct and nourish the existence of their followers, receive from the mystery of Christ the elements of goodness and grace which they contain.

Second Vatican Council, Decree Ad gentes, 9, where it speaks of the elements of good present “in the particular customs and cultures of peoples”‌; Dogmatic Constitution Lumen gentium, 16, where it mentions the elements of good and of truth present among non-Christians, which can be considered a preparation for the reception of the Gospel.
