The most important challenge for the pope and the church is to figure out how to preach the Gospel in a way that is understandable and attractive to people of the 21st century, especially young people, who can be turned off by religion. Benedict got it right when he said Christianity should not be presented as a series of “no’s” but as a “yes” to Jesus and his message of love, life, justice, peace and community. If the new pope does this, he could revitalize the church. He needs to use all the modern means of communication, even Twitter, to get his message across.
In preaching the Gospel, the church needs to imitate, not just quote, great theologians such as Augustine and Thomas Aquinas. Both took the best thinking of their times — for Augustine it was Neoplatonism, for Thomas it was the writings of Aristotle — and used it to explain Christianity.
