ROME (CNN) - Pope Francis is likely to make his next public appearance on Sunday at Saint Peter's Basilica.
On Thursday, during his first full day as pope, he was spotted paying his hotel bill and riding the bus instead of a limo.
That has many Catholics wondering if he's planning to put more cracks in the papal mold.
Francis is well-respected for his austerity and simplicity.
And he was known for washing the feet of the poor, when he was a cardinal.
