Apocalypse Revealed #195
195. "'Which is coming down out of heaven from My God.'" This symbolizes doctrine that will come from the Lord's Divine truth, such as it is in heaven.
Since "My God" symbolizes Divine truth (no. 193), it follows, when it is said of the Lord and of the doctrine of the New Church, that coming down out of heaven from My God symbolizes doctrine that will come from the Lord's Divine truth such as it is in heaven.
Apocalypse Revealed #172
172. "And to the angel of the church in Philadelphia write." (3:7) This symbolically means, to people and concerning people who are governed by truths springing from goodness derived from the Lord.
That these are meant by the church in Philadelphia is apparent from the particulars written to it, understood in their spiritual sense.
