3728. 'And poured oil on the top of it' means holy good [in which it originated]. This is clear from the meaning of 'oil' as the celestial element of love, which is good, dealt with in 886, 3009, and from the meaning of 'the top' as that which is higher, or what amounts to the same, that which is interior - good being that which is higher or interior, and truth that which is lower or exterior, as has been shown in many places. From this one may see what was meant by the ancient practice when people poured oil on the top of a pillar, namely that truth should not be devoid of good but should be grounded in good, thus that good should rule, like the head on top of the body. For truth devoid of good is not truth but is a meaningless sound and the kind of thing that is reduced to nothing. In the next life it is so reduced even with those whose knowledge of truth or matters of doctrine concerning faith, and with those whose knowledge of matters of doctrine concerning love, has been superior to anybody else's, if they have not led a good life and so have not out of a desire for good held on to truth.

[2] Consequently the Church is not the Church by virtue of truth separated from good, nor therefore by virtue of faith separated from charity, but by virtue of truth that is grounded in good, or faith that is grounded in charity. The same is also meant by what the Lord said to Jacob,

I am the God of Bethel, where you anointed a pillar, where you made a vow to Me. Genesis 31:13

Also,

Jacob again set up a pillar, a stone pillar, and poured out a drink-offering over it, and poured oil over it. Genesis 35:14.

'Pouring out a drink-offering over the pillar' means the Divine good of faith, and 'pouring oil over it' the Divine good of love. Anyone may see that unless it meant something celestial and spiritual, pouring oil over a stone would be a ridiculous and idolatrous action.

3009. As to the second point - that Messiah, Anointed, or King is the same as Divine Truth - this is clear from very many places in the Word, and has been shown frequently in explanations; as in 1672, 1728, 2015, 2069. The Lord Himself also teaches the same in John,

Pilate said to Jesus, Are you not then a king? Jesus answered, You say it, because I am a King. For this I was born, and for this I have come into the world, to bear witness to the truth. Everyone who is of the truth hears My voice. John 18:37.

From this it is clear that the Divine Truth itself is at the root of the Lord's being called 'the King'. The reason why kings were anointed and consequently called the anointed was that 'the oil' with which they were anointed meant good, 886, 2832. Also the truth, meant by 'king', was derived from good and was accordingly truth grounded in good, so that the kingly office with them represented the Lord as regards Divine Truth which is derived from Divine Good, and so represented the Divine marriage of good within truth, whereas the priestly function represented the Divine marriage of truth within good. The latter is meant by Jesus, the former by Christ.
