As you may or may not already know, Pope Francis has been in the United States for much of this week. He made appearances in Washington, D.C. and New York before making his way to Philadelphia. As part of the Philadelphia leg of his trip, Pope Francis visited the Festival of Families at Benjamin Franklin Parkway.

Hosting the Festival of Families was none other than Mark Wahlberg. The actor introduced former Eagles running back Herb Lusk, who in 1977 became the first NFL player to kneel and pray after scoring a touchdown and has been a pastor at the Greater Exodus Baptist Church since 1982. Not only did he make the intro, but Wahlberg also got in a quick, "Go Eagles!"

If you're surprised as to why Wahlberg, who is well known as a fan of the New England Patriots, would say such a thing, remember that he portrayed former Eagle Vince Papale in the movie, Invincible.

One of Papale's teammates on the 1976 Eagles, of course, was Herb Lusk, who was selected in the 10th round of that year's draft.
