Saint Patrick is most often recognized for likening the [[Trinity]] to a shamrock, illustrating that the shamrock has three parts, and yet is one; in a similar way, the Trinity has three persons, and is still one God. (cf. the [[OCA]]'s icon^{[[#External Links links and Sources|3]]})

The story of this prayer is that Patrick and his followers used this most beautiful prayer to protect themselves from the people who wanted to kill them as they travelled across Ireland. It is also called the ''Deer's Cry'' (''Fáed Fíada'') because their enemies saw, not men, but deer. It may not have been written by Patrick, but is considered to reflect his theological focus on the Trinity.
