Celtic prayer has a strong Trinitarian tradition. God was God of all of life, so Triune God was involved in everything, from rising in the morning, to tending the sick cow, to banking the fire in the evening.

The simplest, most classic trinity prayer comes from the collection called Carmina Gadelica, first written in 1866 from the oral tradition.
I am bowing my knee
In the eye of the Father who created me,
In the eye of the Son who purchased me,
In the eye of the Spirit who cleanses me.
Mrt was stirred to write my own Trinity prayers in the midst of my needs for every day. I consciously brought all of God into all of my day. I dug into the Bible to see the threefold expression of Father, Son, and Holy Spirit. I was blessed to discover how active he is in our world as he relates in blessed Trinity to his children in the fullness of who he is. How well do you know God the Father, God the Son, and God the Holy Spirit?
Living In The Fullness Of The Trinity, is an invitation into the rich harmonies of our Triune God. Enjoy eight excerpts of the 175 triplets of declaration in the book.

Read these declarations of truth about the majesty and supremacy of God, but don't just read them. Delight in them. They are for intimacy, not just information. Selah. Pause. Don't be so jaded by familiarity that you miss these heart-stopping revelations of God. Let all three Persons of his being plant this deep within you in awe and reverence and wonder. Ask him to show you how to take in the sublime revelation of who he is. Let your spirit receive this from God and then respond from a full and overflowing heart. Don't move on to the next triplet until each one is deep within you.
I am lifting my heart to...
The Three of Intimacy
The Three of Redemption
The Three of Power
Exclaim "How great you are!"
