We are better than we think we are, and we are better off than we think we are. Our faith tells us this in the readings for the Sixth Sunday of Easter.
In the first reading Peter is in the house of Cornelius, a Gentile. According to Jewish teachings, it was wrong for a Jew to enter a Gentile's home, for this would render such a person unclean. This was Peter's concern, but God commanded him to go to Cornelius' home and witness to Jesus.
