100,000 is a big city. People really underestimate how many 100,000 is. 25,000 is a small city, and below 10,000 would be a town. Cities with millions of people are few and far between.
Catholics don’t believe in 3 gods. Imagine a wheel with 3 spokes. At the end of one spoke is written The Father, on another The Son, and the third The Holy Spirit. In the Center of the wheel is written God. The spokes themselves are the word “is”, so it reads as God is (The Father), God is (The Son), and God is (The Holy Spirit). The actual wheel part is the words “is not” written like (The Father) is not (The Son) is not (The Holy Spirit).
Just give peas a chance.
