The guardian Angel accompanies as a faithful ally the divine image in man….the Angel acquits his charge in five ways: he guards, cherishes, protects, visits and defends. He is, therefore, a “flaming star”, a luminous pentagram, above man.
He guards memory, ie, the continuity of the great past in the present, which is the preparation for the great future. It is the guardian Angel who takes care that there is a connection between the great “yesterday, today and tomorrow” of the human soul. He is a perpetual “memento” with regard to the primordial likeness, and with regard to the special room for the soul “in my Father’s house, where there are many rooms.” (John xiv, 2).
If it is necessary, the guardian Angel awakens recollections of the soul’s previous earthly lives, in order to establish continuity of endeavour – of the quest and aspiration of the soul from life to life – so that particular lives are not merely isolated episodes but constitute the stages of a single path towards one sole end.
The guardian Angel cherishes the endeavour, quest and aspiration of the soul engaged on this way [but] support never signifies substitution of the Angel’s will for that of man. The will remains free, always and everywhere.
Just as the guardian Angel is sometimes constrained not to participate in the soul’s activity – this activity not being in accord with the divine image of the soul – so also can he sometimes take a greater part in human activity than usual – this activity being of a nature not simply permitted but also called for. Then the guardian Angel descends from the point of his ordinary post into the domain of human activity. He then visits the human being.
