The Church is herself a missionary disciple; she needs to grow in her interpretation of the revealed word and in her understanding of truth. It is the task of exegetes and theologians to help “the judgment of the Church to mature”.42 The other sciences also help to accomplish this, each in its own way. With reference to the social sciences, for example, John Paul II said that the Church values their research, which helps her “to derive concrete indications helpful for her magisterial mission”.43
Within the Church countless issues are being studied and reflected upon with great freedom. Differing currents of thought in philosophy, theology and pastoral practice, if open to being reconciled by the Spirit in respect and love, can enable the Church to grow, since all of them help to express more clearly the immense riches of God’s word. For those who long for a monolithic body of doctrine guarded by all and leaving no room for nuance, this might appear as undesirable and leading to confusion. But in fact such variety serves to bring out and develop different facets of the inexhaustible riches of the Gospel.44

44 Saint Thomas Aquinas noted that the multiplicity and variety “were the intention of the first agent”, who wished that “what each individual thing lacked in order to reflect the divine goodness would be made up for by other things”, since the Creator’s goodness “could not be fittingly reflected by just one creature” (S. Th., I, q. 47, a. 1). Consequently, we need to grasp the variety of things in their multiple relationships (cf. S. Th., I, q. 47, a. 2, ad 1; q. 47, a. 3). By analogy, we need to listen to and complement one another in our partial reception of reality and the Gospel.
