2811. 'And Abraham built the altar there' means preparation of the Lord's Divine human. This is clear from the meaning of 'the altar' and of 'building the altar'. Altars used to mean all worship in general because they were the chief feature of the worship of the representative Church, 921. And because they meant all worship in general they meant the Lord's Divine Human, for the Lord's Divine Human is essentially present in all worship and all doctrine, so much so that it is the very essence of worship itself and doctrine itself. This becomes clear also from the Holy Supper which superseded altars, that is, burnt offerings and sacrifices, 2165, 2187, 2343, 2359. The Holy Supper is the chief feature of external worship because it is the Lord's Divine Human that is bestowed there. From all this it may become clear, and so without further explanation, that 'building an altar' means preparing the Divine human. The final preparation of the Lord's Divine human for undergoing the last degrees of temptation is the subject in the present verse and is described by the statement that Abraham laid the pieces of wood in order, bound Isaac his son, and laid him on the altar, upon the pieces of wood.

203. Spiritual angels however do discuss faith; they even confirm matters of faith by means of intellectual concepts, rational concepts, and factual knowledge. But they never use these as a means to arrive at a conclusion concerning faith. Those who do that are under the influence of evil. For spiritual angels also have from the Lord a perception of everything that is a matter of faith, but the nature of their perception is not the same as that of celestial angels. The perception that spiritual angels have is a measure of conscience vitalized by the Lord. It seems like celestial perception, but it is merely spiritual perception and not celestial.
