Each individual is endowed with gifts for building up the community; learning is also a precious gift, especially when it is profound and systematic. To bear fruit that benefits those who possess it and their brethren, it also needs to be enriched with love, without which the possession of all knowledge is useless.
Love should be accompanied by simplicity of heart, which belongs to those whom the Gospel, echoing the Lord Jesus' words, calls "children". "I offer you praise, O Father, Lord of heaven and earth, because what you have hidden from the learned and the clever you have revealed to the merest children." This marvelous blessing, which springs from Christ's heart, reminds us that genuine intellectual maturity always goes hand in hand with simplicity. The latter does not consist in a superficiality of life and thought nor in denial of the problematic nature of reality, but rather in knowing how to go to the heart of every question and to discover its essential meaning and relationship to the whole. Simplicity is wisdom.
--Pope John Paul II, November 1998
