(KCEN) -- A huge crowd packed Saint Peter's Square at the Vatican for one of Pope Benedict's final Sunday prayer services.
The 85-year-old pope announced last week he will be stepping down on February 28th due to advancing age.
The Vatican estimated the crowd at more than 50,000 people but local authorities put it at twice that.
He also tweeted a message to followers worldwide, calling on them to rediscover faith as a foundation.
