630. THAT THE ANGELS ARE ALWAYS BEING PERFECTED, BUT THEY CAN NEVER BE PERFECT OR HOLY However much souls are admitted into the more interior and inmost heaven, still they are not perfect, but there always adheres something natural which must be amended. This is effected when they are sent back among spirits. It then at once appears what residue from the natural root they still retain, and this is then amended. And so it continues through many times of being sent back, so that it is a rule that an angel can never be so perfected to eternity that he can be said to be perfect and holy. The only one who is perfect and holy is the Lord who is Perfection and Holiness itself. 1748, Feb. 2.
