The Cloud of Unknowing, Prologue
ALMIGHTIE God, unto whom all hartes bee open, and all desyres knowen, and from whom no secretes are hid: clense the thoughtes of our hartes, by the inspiracion of thy holy spirite: that we may perfectly love thee, and worthely magnifie thy holy name: through Christ our Lorde. Amen.
Book of Common Prayer (1549)
OMNIPOTENS Deus, cui omne cor patet, & cui omnes affectus animorum cogniti sunt, & quem nihil latet, purifica cogitationes cordium nostrorum, ut per inspirationem Sancti Spiritus te ex animo amemus, & debita veneratione celebramus Nomen tuum sanctum, Per Jesum Christum Dominum nostrum.
