The Hypostatic Union of the two natures of Christ is like a Black and Tan (a kind of alcoholic drink):
"The hypostatic union is kind of like this black and tan," I began.
I was barely finished saying the phrase when at once I could see their eyes light up, ears perk, and both men seemed to lean a little close to me. At the thought of mixing religion and beer and their reactions to my opening comment, I knew I was speaking their language. I continued:
"You see, Christ was both true man and true God. That is, He has two different natures. Just like this Black and Tan has two different natures -- or styles -- of beer within its glass. Yet, even though there are two styles of beer in a Black and Tan they are both contained in the one drink that is called a Black and Tan. Likewise, Christ's two natures are both found in the one Person called Jesus of Nazareth.
