O blessèd Holy Trinity,
Divine, eternal Unity,
God Father, Son and Holy Ghost,
Be Thou this day my Guide and Host.

My soul and body keep from harm,
O’er all I have extend Thine arm,
That Satan may not cause distress
Nor bring me shame and wretchedness.

The Father’s love shield me this day,
The Son’s pure wisdom cheer my way,
The Holy Spirit’s light divine
Illume my heart’s benighted shrine.

My Maker, strengthen Thou my heart,
O my Redeemer, help impart,
Blest Comforter, keep at my side
That faith and love in me abide.

Lord, bless and keep Thou me as Thine;
Lord, make Thy face upon me shine;
Lord, lift Thy countenance on me
And give me peace, sweet peace, from Thee.
