10370. 'And the children of Israel shall keep the sabbath, observing the sabbath [throughout] their generations' means that the truly essential thing of the Church is the acknowledgement of the union of the Divine itself within the Lord's Human, and that this acknowledgement must be present in every single part of worship. This is clear from the meaning of 'keeping the sabbath' as thought which is holy and goes on unceasingly regarding the union of Divinity itself to the Lord's Human, dealt with above in 10356, and so also acknowledging it, for thinking without acknowledging and believing is not spiritual thinking; from the representation of 'the children of Israel' as the Church, dealt with in the places referred to in 9340; from the meaning of 'observing the sabbath' as worshipping that union in a holy way and so worshipping the Lord's Divine Human, since that union resides within His Human; and from the meaning of 'the generations of the children of Israel' as in every single thing of the Church, dealt with in 10282. From all this it is evident that 'the children of Israel shall keep the sabbath, observing the sabbath [throughout] your generations' means maintaining the acknowledgement of Divinity itself within the Lord's Human in every single part of worship. The reason why this is the essential thing of the Church and consequently of its worship is that the salvation of the human race depends solely on that union. For the sake also of this union the Lord came into the world; and therefore also that is what the whole Word in its inmost sense deals with and what the religious observances of the Church established among the children of Israel represented and meant spiritually.
