In an ecology of love, people can relate in trust and face the future without fear. They do not need to play it safe. They can take uncertainty in their stride.

There are hard texts in each tradition which we must confront and ask ourselves, 'Can we reinterpret those texts to allow us to live peaceably, and respectfully, with people of other faiths?' That is a job only Jews can do for Judaism, only Christians can do for Christianity, and only Muslims can do for Islam. But sometimes the sight of someone in one faith wrestling with that faith can empower you to wrestle with another faith.

Sometimes the sight of someone in one faith wrestling with that faith can empower you to wrestle with another faith. For me, it was reading about how the Catholic Church wrestled with itself in the 1960s. Pope John XXIII set Nostra Aetate - the Declaration on the Relation of the Church with Non-Christian Religions - in motion. It changed the relationship between Jews and Catholics.
