Gossiping about someone is a “dark joy” that Christians must resist because it is a betrayal like Judas’ betrayal of Jesus, Pope Francis says.

While the pope celebrated Mass in his residence, as has been his custom, several thousand Vatican employees were at Mass in St. Peter’s Basilica. The employees’ Mass on Wednesday of Holy Week is a Vatican tradition.

The Domus Sanctae Marthae is directly across a small parking lot from the sacristy entrance to the basilica. At the end of the Mass, celebrated by Cardinal Angelo Comastri, of the basilica, Pope Francis walked over to greet the employees.

The pope thanked them for their service, and said: “I ask you to pray for me. I need it because I am a sinner, too, like everyone and I want to be faithful to the Lord. Pray for me.”
