From the Apostolic Letter "Aperuit Illis" of Pope Francis
'…At the conclusion of the Extraordinary Jubilee of Mercy, I proposed setting aside "a Sunday given over entirely to the word of God, so as to appreciate the inexhaustible riches contained in that constant dialogue between the Lord and his people". Devoting a specific Sunday of the liturgical year to the word of God can enable the Church to experience anew how the risen Lord opens up for us the treasury of his word and enables us to proclaim its unfathomable riches before the world…
'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.
'The various communities will find their own ways to mark this Sunday with a certain solemnity. It is important, however, that in the Eucharistic celebration the sacred text be enthroned, in order to focus the attention of the assembly on the normative value of God's word. On this Sunday, it would be particularly appropriate to highlight the proclamation of the word of the Lord and to emphasize in the homily the honour that it is due. Bishops could celebrate the Rite of Installation of Lectors or a similar commissioning of readers, in order to bring out the importance of the proclamation of God's word in the liturgy. In this regard, renewed efforts should be made to provide members of the faithful with the training needed to be genuine proclaimers of the word, as is already the practice in the case of acolytes or extraordinary ministers of Holy Communion. Pastors can also find ways of giving a Bible, or one of its books, to the entire assembly as a way of showing the importance of learning how to read, appreciate and pray daily with sacred Scripture, especially through the practice of lectio divina.'
