3420. 'Which the Philistines had been stopping up after Abraham's death' means that people who had no more than a knowledge of cognitions refused to recognize these truths. This is clear from the meaning of 'stopping up' as not wishing to know, and what amounts to the same, refusing to recognize and so effacing, dealt with above in 3412; and from the representation of 'the Philistines' as those who have no more than a knowledge of cognitions, dealt with in 1197, 1198, 3412, 3413. It is the knowledge of cognitions that those ruled by matters of doctrine concerning faith possess, and they have no wish to know the truths that are the sources of cognitions or matters of doctrine. The truths that are the sources of cognitions or matters of doctrine are those that have to do with life and that have regard to charity towards the neighbour and love to the Lord. Religious teaching, which consists of matters of doctrine and of recognized facts, does no more than teach those things. Anyone therefore who teaches what ought to be done, but does not do it himself, does not wish to know truths since they run counter to his life. And things contrary to his life he also refuses to recognize. These are the reasons why the matters of doctrine concerning love and charity which in the Ancient Church constituted the whole of religious teaching have been effaced.

2632. 'Abraham circumcised his son Isaac' means purification of the rational. This is clear from the meaning of 'being circumcised' as being purified, dealt with in 2039, and from the representation of 'Isaac' as the Divine Rational, dealt with in 2630.

[2] The Lord's first rational was born in the way it is with others, that is to say, by means of facts and cognitions. This has been stated already where Ishmael, who represents that rational, is the subject. Because it was born, as with others, by means of facts and cognitions, thus by the external way, which is that of the senses, this rational inevitably included many things that were worldly in origin, for it is from those things that the ideas which the rational possesses are acquired. This was even more so the case with the Lord on account of the heredity He had from the mother. It was those worldly things and this heredity which the Lord gradually cast out of His rational until it was such that it was able to receive the Divine, 2624, 2625. At this point the Lord's Divine Rational, represented by 'Isaac', was born, 2630, not indeed by the external way, which is that of the senses - as was the case with the previous rational - but by the internal way from the Divine itself, 2628, 2629. As this was not accomplished all at once but gradually, 1690, 2033, the rational was purified, and constantly so. It is this purification that is meant by 'Abraham circumcised his son, a son eight days old'. That the Lord gradually made His Rational Divine and purified it constantly is clear also in John,

Jesus said, Father, glorify Your name. A voice therefore came from heaven, I have both glorified it, and will glorify it again. John 12:28.

'Glorifying' is making Divine, see 1603, 1999.

[3] In the Ancient Church nothing else was represented and meant by circumcision than that a person should be purified from self-love and love of the world, which is also effected gradually and constantly, see 2039, 2046 (end), 2049, 2056, especially when a person has been born anew or regenerated. For at that time the Lord is flowing in by the internal way, that is, through the good that forms part of conscience; and He gradually and constantly separates the things which cling to that person both as a result of hereditary evil and of the evil of his own doing.
