St Peter's Basilica - Body of Blessed John XXIII
The not so Incorrupt body of Pope John XXIII (1958-63), known as 'good Pope John' and probably the most loved Pope of all time.
According to the reliable source, www.traditio.com - John XXIII in a massive reaffirmation of traditional practice, solemnly confirmed the use of Latin, condemned all attempts at creativity on the part of the celebrant of Holy Mass, ordered Gregorian Chant, and forbade women entry to the altar area.
He was beatified on September 3, 2000.
Pope John's body is NOT Incorrupt. His excellent state of preservation is due to embalming.
