Football, Polamalu said, "gives me confirmation of how I can carry out my faith. It's my way to glorify God."

And while he views his team's 2006 Super Bowl win as "really beautiful and a blessing," Polamalu notes that "success in football doesn't matter. Success in anything doesn't matter. As Mother Teresa said, God calls us not to be successful but to be faithful. My prayer is that I would glorify God no matter what, and not have success be the definition of it."

"Knowing Troy and how he carries himself, he brings light to the team," offensive lineman Alan Faneca told the Pittsburgh Catholic, the official publication of the Diocese of Pittsburgh. "Everybody respects that."

Polamalu exudes a gentle, humble spirit, said Father David Bonnar, pastor of St. Bartholomew Parish in the Pittsburgh suburb of Penn Hills, who has celebrated Mass for 10 years before home games with Steelers players and coaches.

"Since his arrival in Pittsburgh, he has been a permanent fixture at Mass. Even with all of the fame and success, Troy remains committed to the Christian faith," Father Bonnar said. "And if he has changed in any way, he has just become even more humble and spiritual. I have found him to have both the strong contemplative sense of Mary and the fierce active sense of Martha."

Raised in Tenmile, Ore., the youngest of five children, Polamalu attended Catholic grade school and was steeped in the Polynesian culture of reverence for family, church and personal honor.

"I believe that I'm the same person on and off the field. I live my life with a passion and that includes how I play. Obviously, football calls for physical contact, but that's just part of the game," Polamalu said.

To illustrate, he offers Jesus' time on earth as an example. "Look at the passion for life that he lived as portrayed in the Stations of the Cross – that fight that he had in him, as well as the love he shared with others. There's no difference."

Indeed, what sets Polamalu apart is his knack for keeping love at the center of his sport. "Football, in general, has it backwards," he said. "They think this inner anger, this hatred, is what drives football and becomes the physical aspect of the game. But love overcomes all things. My love to glorify God through my playing will far outweigh anybody's hate for me."

For New York Giants kicker Jay Feely, it was an unmistakable moment of clarity that solidified his Catholic faith and revealed his true mission in life.

Feely's epiphany occurred Jan. 1, 1998, in Pasadena, Calif., just hours after his college football team, the University of Michigan Wolverines, defeated Washington State 21-16 to win the Rose Bowl, capping a perfect 12-0 national championship season.

The raucous post-game celebration at the team's hotel that New Year's Day was just a noisy backdrop for Feely's encounter with a 10-year-old boy who was dying of a brain tumor. The boy's mother had brought him to meet Feely after the game.

In the week leading up to the Rose Bowl, Feely had volunteered to speak with inner-city kids as part of a community outreach program. This woman had attended Feely's speaking engagement, where he discussed his Catholic faith. Inspired by Feely's presentation, she sought him out to speak with her son.

"He knew he was very ill," Feely told the Catholic Advocate, the official newspaper of the Archdiocese of Newark, N.J., recalling his impromptu meeting with the boy. "I told him God had a purpose for him; that God has a plan for everyone."

The kicker and the boy connected, albeit briefly, amid the hoopla in the hotel lobby. Feely recalled seeing a visible, remarkable difference in the boy's appearance and expression – evidence that Feely's words somehow had touched a chord.

"I think about the impact I had on that little boy," said Feely, who was second in the NFL last season with 148 points, sitting in the locker room of Giants Stadium in East Rutherford, N.J. "That was my moment of clarity. It solidified my faith. That was when I understood my life as a man, how I could use football to affect people's lives in a positive way. God gives us different gifts."

For Minnesota Vikings backup quarterback Mike McMahon, a lifelong Catholic, his test of faith came during his junior year in college, as starting quarterback for Rutgers University in New Jersey.

"I blew my shoulder out and tore my rotator cuff," he told The Catholic Spirit, the official newspaper of the Archdiocese of St. Paul-Minneapolis, at Vikings training camp in Mankato, Minn. "I had to go to surgery. Everyone I talked to said, 'That's it. It's your throwing arm. You're done. Your career is over.'"

Then, the day before surgery, his father, Robert, suffered a heart attack and was told he would need a quadruple bypass. He ended up at the same hospital as his son.

"My mom (Patricia) was running up and down floors," McMahon said. "His surgery was 100 times more serious; mine was 100 times more painful. That's what the doctor said. It was one of the most painful experiences I've ever went through. After (the surgery), the pain was unbearable. I had to sleep in a recliner for three months straight, sitting up because I couldn't lay back because of the pressure."

The pain got so bad he would call his parents in the middle of the night crying. He had trouble concentrating in school because of the pain and had to drop classes. On top of that, there was the nagging question of whether he would ever play again.

McMahon said he questioned God and his faith but never abandoned either. Inspired by his grandfather, Edward Zilian, who battled cancer for years before finally succumbing the same year as McMahon's surgery, he worked aggressively to rehabilitate his shoulder. The following season, he was back in the lineup.

"I wouldn't have been able to make it through if it wasn't for having faith in God," McMahon said. Six years later, he continues to draw upon his faith. He carries a rosary with him and prays three prayers every day: the Our Father, the Hail Mary and the Memorare, which he recited from memory while standing near the practice field. McMahon's father taught him the prayer when he was in high school and he has said it daily since.
