Hear me out.
So, I saw this in a reddit post from 8yrs ago when I was looking up the meaning for "entertain my faith":
"His(Tyler) dad was the principle at my school (a christian school) and around the time vessel came out his father gave us a message about God and such. But in the message he told us the song was about holding onto God and his christian roots. Entertain my faith means he wants God to please him by proving He is real and showing him his power." - reddit user
After seing this post something clicked in my head.
I think: "its a breach" is a breach of trust between Tyler and God.
"I wonder where you are, I wanted you to show me" is him seaching for a connection with God/Jesus.
"The way around those city walls, a way on through" is a reference to the Kingdom of Heaven and the gates and being welcomed in.
"Abandonded by the Sun" or "Son" is a reference to Jesus(Son of God), which he feels abandoned by.
Then, add the reference back to "entertain my faith" and how Tyler is looking for God to show himself, the lryic of "this is the last time I address my soul" really makes the breach of trust(in his eyes) more apparent and shows how hurt he is trying to navigate his head/life by himself. He feels abandoned by God/Jesus.
To me this is Tylers struggle with his own faith.
Since I listened to City Walls thru this lense, it makes perfect sense. Eitherway, its such a masterpiece how he can tell 2 stories at once.
Let me know y'alls thoughts.
