Even with modern scientific technology, the Shroud of Turin continues to baffle researchers.
Barrie Schwortz was the documenting photographer for the Shroud of Turin research project in 1978, an in-depth examination of what many people believe to be the burial cloth of Jesus.

"Isn't it funny how God always picks a Jew to be the messenger," he said.

Catholics need to know that marrying someone from a different Christian community or, even more so, from a different religion will create extra challenges in their marriage, but church leaders also must learn how to help people in mixed marriages meet those challenges, a Vatican official said.
"We can express a positive judgment only when the conditions are met for a family life where the values and purposes of marriage are respected, and where a common faith in God helps the spouses to weave together an authentic communion of life and love," said Bishop Jean Laffitte.
