In the 1st reading, we heard that after Jesus was taken up to heaven, the apostles returned to Jerusalem and went to the upper room where they were staying
There they devoted themselves with one accord to prayer, together with some women, and Mary the mother of Jesus.
That was the last mention of Mary. After that there was no more mention of her in the rest of the Bible.
This last mention of Mary is significant because that was also her purpose after Jesus was taken up to heaven.
Mary stayed with the apostles and she was with them in prayer. She was doing this because she was obedient to what Jesus entrusted to her while He was on the cross.
Because Mary remembered what Jesus told her when He was on the cross: Woman, behold your son.
Though she did not reply, her silence was her consent. She not only agreed to be the mother of the disciple that Jesus loved, she understood that she was to be the mother of all the disciples of Jesus.
Today's memorial of Mary, Mother of the Church, is a new addition to the liturgical calendar of the Church.
That title of Mary, Mother of the Church, was officially given to Mary during the Second Vatican Council by Pope Paul VI.
So from Mother of God, she is now also the Mother of the Church. And if we are obedient to what Jesus said on the cross, then we too must embrace Mary as our Mother, which most of us would be more willing to do.
But for us, Mary is not just our Mother, but we would also want to carry out what Jesus entrusted to us and we want Mary to be the Mother of all peoples.
As we celebrate this memorial, let us make our Mother known to all peoples, for in doing so, we are also making Jesus known to all peoples.
