you called Luke the physician,
whose praise is in the gospel,
to be an evangelist and physician of the soul:
by the grace of the Spirit
and through the wholesome medicine of the gospel,
give your Church the same love and power to heal;
through Jesus Christ your Son our Lord,
who is alive and reigns with you,
in the unity of the Holy Spirit,
one God, now and for ever.
