Arcana Coelestia # 10111
10111. 'To sanctify them' means in order that they may be in possession of truths from good which come from the Lord. This is clear from the meaning of 'being sanctified' as representing the Lord and the holy things which come from Him, dealt with in 9956, 9988, and so in the spiritual sense as being led by the Lord, since the Lord alone is holy and He is the source of everything holy, 8806, 9229, 9479, 9688, 9818, 9820. From this it is evident that receiving truths through good from the Lord, thus receiving faith through love derived from Him and shown towards Him, is meant by being sanctified. Not that the person regarded in himself is therefore holy; only the Lord present with Him is holy. For faith and love constitute the Lord's presence with a person, since He is the one to whom unceasingly they owe their existence.

9469. 'And fine linen' means the truth from this, that is to say, from the good which has a celestial origin. 'Flax' or 'linen' means truth, see 7601, and 'fine linen' means truth from the Divine, 5319; both kinds of truth exist in the natural man. 'Fine linen' means truth from a celestial origin because of its whiteness and softness.
