The Intention of the Holy Father for September is for parishes at the service of the mission:
“That they not be simple offices, but that animated by a missionary spirit, may be places where faith is communicated and charity is seen.
Parishes must be in contact with homes, with people’s lives, with the life of society.
They have to be houses where the door is always open so as to go forth toward others.
And it is important that this going-forth follows a clear proposal of faith.
The doors must be opened so that Jesus can go out with all of the joy of his message.
Let us pray for our parishes, that they not be simple offices, but that animated by a missionary spirit, may be places where faith is communicated and charity is seen.”
