Bearing in mind the Benedictine inspiration of the life and work of Fr. Jaki, the motto of the Foundation is:
Ut in omnibus glorificetur Deus
In English this can be rendered:
See 1 Peter 4:11, quoted by St. Benedict in Chapter 57,9 of his Rule.
See also St. Gregory of Nazianzus, The First Theological Oration, 1, 3:
Δεἳ γᾲρ τᾣ ὂντι σχολάσαι, καὶ γνὣναι ϑεόν
For it is necessary to be truly at leisure to know God.
