The opening chapter of the church's most sacred moment of the year, while the rite normally takes place in at St John Lateran, this year's Evening Mass was previously slated to happen in the Vatican Basilica as the new pontiff has yet to take possession of the Lateran – the "Mother and Head" of all churches, which technically serves as the cathedral of the bishop of Rome.
Historically, at the Evening Mass the Popes have washed the feet of 12 retired priests of their diocese.
In its release, the Vatican noted that the later Holy Thursday Mass "is characterized by the announcement of the Commandment of love and the act of the washing of the feet.
"In his ministry as archbishop of Buenos Aires, [then-]Cardinal Bergoglio would celebrate this Mass in a jail, a hospital or a home for the poor or marginalized people," the release said (prior instances above).
"With the celebration at the Casa de Marmo [facility], Pope Francis continues this use, one that can only be characterized in a context of simplicity."
As previously scheduled, the Pope will still celebrate the mid-morning Chrism Mass – dedicated to the institution of the priesthood and the consecration of his diocese's oils for the year – in its usual venue at St Peter's.
