Angelus Silesius describes the mystical deification of the human soul as its inclusion in the Trinity. He uses traditional comparisons and metaphors, as formed on biblical basis by the Fathers to illustrate the inner Trinitarian relations, but also geometric and naturalistic analogies to lead the soul in three ways into God. These are always figurative appellations which, paradoxically, according to negative theology, can also be negated for the very essence of God, which remains unnameable. In this mystical unity, which in the teaching of the church can only happen by grace, but not in a pantheistic fashion by nature, man preserves the creaturely difference to the Creator. Even in the earliest epigrams, Scheffler’s Catholic point of view is that God cannot resist this union of love, and that therefore only man, with his free will, is responsible for its success. The model of the saints and the ethical demand for the keeping of the commandments and the doing of the good works, which confirm the authenticity of this mysticism as well as their conformity with the ecclesiastical tradition, also fit in with this result.
