The former Muslim who converted to Christianity says his life is in danger.
Pope Benedict baptized Magdi Allam during a world-wide broadcast over the weekend.
Allam, 55, deputy editor of Corriere della Sera newspaper, was born a Muslim in Egypt, but was educated by Catholics and says he has never been a practicing Muslim.
He wrote in a front-page letter published Sunday in Corriere that he was now taking on the middle name Cristiano - Christian in Italian.
He expressed his gratitude to Benedict, calling Saturday "the most beautiful day of my life."
"The miracle of the resurrection of Christ reverberated in my soul, freeing it from the shadows of a preaching where hate and intolerance toward he who is different, toward he who is condemned as an 'enemy,' prevailed over love and respect for your neighbor," Allam wrote.
But he says he realized it would lead to a death sentence under Islamic law for abandoning his faith.
Allam says he's willing to take that risk because he's finally seen the light, thanks to what he calls divine grace.
