Arcana Coelestia # 437
437. Here 'Seth' means new faith, by way of which comes charity. This is explained by his very name, which he received because 'God has appointed another seed in place of Abel, seeing that Cain had killed him'. 'God has appointed another seed' means that the Lord conferred another faith. 'Another seed' is faith by way of which charity may be received. That 'seed' means faith, see what has been stated already in 255.
Eve
The name 'Eve' comes from the Hebrew word חַוָּה or 'Chava,' a form of the word for life, which is why she is called 'the mother of all living.' She represents the church, and is called 'mother' because this was the first Church of all, and 'living' because of its faith in the Lord, who is life itself.
