My translation from the Italian:
O Father, we give you thanks
for the Christian testimony of Chiara Badano
Animated by your Spirit and intimately united with Jesus,
she revealed that the ideal of life is love
and in love she joyfully offered her youth
for the mission of the Church.
If it is your will, grant that Chiara be
recognized as "venerable"
for the building up of the faithful.
We ask this of you through the merits of Jesus Christ, our Lord. Amen.
The prayer was expanded, and now here’s the new translation given on the website:
O Father, beginning of all good,
Who for the merits of your Son Jesus
Bring wonders of goodness
To those who confide in your love,
we give you thanks
for the Christian testimony of Chiara Badano.
Animated by your Spirit,
in her union with Jesus, she found the light
to recognize that love is the ideal of life,
and the strength to carry out,
in total abandonment to your will
the offering her youth
for the mission of the Church.
If it is your will, grant that Chiara be
recognized as "venerable"
for the building up of the faithful,
we ask you the grace …
for the elevation of your Fatherly goodness.
We ask this of you through the merits of Jesus Christ, our Lord.
Amen.
Update: She is now a “Venerable Servant of God.” Change “Venerable” to “Blessed.”
