On 30 September 2019, Pope Francis, by the Motu Proprio Aperuit Illis declared the Third Sunday of Ordinary Time to be the Sunday of the Word of God.
“… It is fitting, then that the life of our people be constantly marked by this decisive relationship with the living word that the Lord never tires of speaking to his Bride, that she may grow in love and faithful witness. Consequently, I hereby declare that the Third Sunday in Ordinary Time is to be devoted to the celebration, study and dissemination of the word of God. This Sunday of the Word of God will thus be a fitting part of that time of the year when we are encouraged to strengthen our bonds with the Jewish people and to pray for Christian unity. This is more than a temporal coincidence: the celebration of the Sunday of the Word of God has ecumenical value, since the Scriptures point out, for those who listen, the path to authentic and firm unity” (Pope Francis, Apostolic Letter, Aperuit Illis, nos 2-3, dated September 30, 2019)
This Sunday 21st January is the Word of God. It is devoted to the celebration, study and dissemination of the word of God.
