New Marian Feast

Today is the new Feast of Mary, Mother of the Church, established by Pope Francis earlier this year.
It will be celebrated each year on Monday following the Solemnity of Pentecost. Prior to the liturgical renewal of the Second Vatican Council this week was the Octave of Pentecost. There remain only two octaves, Christmas and Easter.
