As a protective device, I think this beats wearing green. An excerpt from the Lorica, or Breastplate of St. Patrick:

Críst limm, Críst reum, Críst im degaid
Críst indium, Críst íssum, Críst úassum
Críst dessum, Críst túathum
Críst i llius, Críst i ssius, Críst i n-érus
Críst i cridiu cach duini rodomscrútadar
Críst i ngiun cach oín rodomlabrathar
Críst i cach rusc nomdercadar
Críst i cach clúais rodomchloathar.

In the Sasanach tongue, by way of Mrs. Cecil Frances Humphreys Alexander:

"Christ be with me, Christ within me,
Christ behind me, Christ before me,
Christ beside me, Christ to win me,
Christ to comfort and restore me,
Christ beneath me, Christ above me,
Christ in quiet, Christ in danger,
Christ in hearts of all that love me,
Christ in mouth of friend and stranger.

"I bind unto myself the name,
The strong name of the Trinity;
By invocation of the same.
The Three in One, and One in Three,
Of whom all nature hath creation,
Eternal Father, Spirit, Word:
Praise to the Lord of my salvation,
salvation is of Christ the Lord."
