Those who are in prison are often abandoned and given less consideration, but they have always been close to the heart of Pope Francis who has spoken numerous times about their situation: “The inmates are serving a sentence, a sentence for a mistake they have made. But let us not forget that for punishment to be fruitful there must be a horizon of hope; otherwise it remains closed in on itself and is simply an instrument of torture; it is not fruitful. Punishment with hope, so it is fruitful.” During his homily for Midnight Mass last December 24, Pope Francis spoke again about them: “In the Child of Bethlehem, God comes to meet us and make us active sharers in the life around us. He offers himself to us, so that we can take him into our arms, lift him and embrace him. So that in him we will not be afraid to take into our arms, raise up and embrace the thirsty, the stranger, the naked, the sick, the imprisoned (cf. Mt 25:35-36)”. The theme of prison inmates is important also for the Philatelic Office of Vatican City, especially in recent years, through its participation in philatelic initiatives taking place at the Opera prison in Milan, Italy. We are very pleased to announce that this year’s series of commemorative postage stamps for Christmas have been produced by a prison inmate from that facility, Mr. Marcello D’Agata.
