For Earth Day, we welcome back Boston Law Professor Jay Wexler to talk about his recent book, When God Isn't Green, which finds him exploring the points around the globe where religion and environmentalism come into conflict.

Around the world, Catholic and Protestant Christians are making preparations for Holy Week, a series of worship services leading up Easter, the day that Christians proclaim Jesus Christ was raised from the dead. During the day known as Good Friday,there is a tradition in many Christian communities to reflect on a series of phrases known as the "Seven Last Words" of Jesus as he hung on the cross.

We speak with Fr. James Martin about his book, Seven Last Words, a collection of his meditations on the final hours of Jesus, and what it means for believers and nonbelievers alike.
