[2] From this it is evident what to understand when the adjective 'holy' is applied to the words 'angels', 'prophets', and 'apostles' - to 'angels' in Matt 25:31; Mark 8:38; Luke 9:26; to 'prophets' in Rev 16:6; 18:24; and to 'apostles' in Rev 18:20. They were holy not by virtue of anything their own, only by virtue of what was the Lord's. Angels are called holy because they are recipients of Divine Truth emanating from the Lord, for which reason they mean in the Word God's truths, and in general something that is the Lord's, 1925, 2821, 4085, 4295. But prophets are called holy because the Word, which is Divine Truth, and in particular teachings drawn from the Word, is meant by them, 2534, 3652, 7269; and apostles because every truth of faith and good of love in their entirety are meant by them, 3488, 3858 (end), 6397.

[3] The fact that Divine Truth emanating from the Lord is Holiness itself, thus is the Lord who is its Source, is clear from a large number of places in the Word, of which for now let just the following words of the Lord in John be quoted,

Father, make them holy in Your truth; Your Word is truth. For their sakes I make Myself holy, that they also may be made holy in the truth. John 17:17, 19.

From this it is evident that the Lord is the One who makes man, spirit, and angel holy, for He alone is Holy, Rev 15:4, and that they are holy in the measure that they receive the Lord, that is, in the measure that they receive from Him the power to believe in Him and to love Him.
