The Vatican also announced today the particular themes which will be explored on particular days throughout the week including, “United through the presence of Christ, ‘One Lord, one Faith, one Baptism;’” “Building Christian unity with Jesus in our midst - daily ecumenism, ‘You also ought to wash one another's feet;’” and “Praying together in Jesus' name, ‘The Lord waits to be gracious to you.’”
Themes for the latter half of the celebration will include, “From the past to the future - forgiveness and healing of memories Not seven times, but, I tell you, seventy times seven,’” taken from the Jesus words in the Gospel of Matthew; “God's presence among us: a call to peace. ‘The Lord is with us;’” “Mission in Jesus' name. ‘So it is not the will of your Father in heaven that one of these little ones should be lost;’” and “Recognizing and welcoming God's presence in the other in Jesus' name,
’Whoever welcomes one such child in my name welcomes me.’”
On January 25th, the last day of the celebration, faithful will be asked to meditate on the theme: “One in hope, "On that day you will know that I am in my Father and you in me, and I in you," taken from John 14:20.
Each of the days takes their theme from Scripture.
