Apocalypse Explained #230
230. Verse 15. I know thy works, signifies the life of faith alone. This is evident from the signification of "works," as being the things that are of man's interior life, for works proceed from these and are their effects (See above n. 157-185); here, therefore, they signify the life of faith alone, because this is treated of in what is written to this church. To each of the churches it is said first, "I know thy works," and in every case "works" signify the things of the church there treated of (See above, n. 98); therefore what now follows describes what the life of faith alone is or the life of faith separate from charity.
Arcana Coelestia #4520
4520. 'I and my house' means as regards truth and good. This is clear from the representation of Jacob, to whom 'I' refers here, as the Church, in particular the Church as regards truth (as may be deduced from what has been shown concerning Jacob's representation in 3305, 3509, 3525, 3546, 3576, 3599, 3775, 4234, 4337; that is to say, he represents the Lord as regards Divine Natural Truth. For in representations when a person in the highest sense represents the Lord as regards the Divine Truth of His Natural, he also represents the Lord's kingdom as regards Divine Truth there, and consequently the Church as regards truth, because these correspond to each other; for all truth within His kingdom and Church is the Lord's); and from the meaning of 'a house' as the Church as regards good, dealt with in 2233, 2234, 3720.
