Benedict's homily was an unusually politicized papal message during Mass.
Benedict said people find freedom when they seek the truth that Christianity offers. He added, "On the other hand there are those who wrongly interpret this search for the truth, leading them to irrationality and fanaticism; they close themselves up in 'their truth' and try to impose it on others."
He didn't cite the government by name in Wednesday's message, but later urged Cuba to let the church more freely preach its message.
