Today is the Feast of St Columba of Iona

O God, who called your servant Columba
from among the princes of Ireland
to be a herald and evangelist of your kingdom:
grant that your Church, remembering his faith and courage,
may so proclaim the gospel,
that people everywhere
will come to know your Son as their Saviour,
and serve him as their king;
who lives and reigns with you,
in the unity of the Holy Spirit,
one God, world without end.  Amen
