1. God created all things. In this sense he is a father.
2. He permeates all of his creation. In this sense he is a spirit.
3. He took human form. In this sense he is a son.
These are all manifestations of the same omnipotent God, and such things should certainly be possible for any omnipotent being. Seriously guys, the trinity is as basic as it gets. Of all the things we could seek to understand about the proposed nature of God it's the easiest to comprehend. So why do people carry on as if it's some kind of sophisticated philosophical absurdity?
I'm an atheist myself. But carrying on about how the trinity doesn't make sense just makes atheists (or anyone else) look unintelligent, which is why I'm responding.
Regarding the video, the caller was asking valid questions. The host is just a fucking moron who knows very little about his own religion.
