The Baltimore Catechism is on the same intellectual level as Dick and Jane. For example, it takes about a dozen lines to describe the Trinity. Perhaps you have heard the story that as Augustine was writing On the Trinity, he saw a boy on a beach pouring seawater into a hole. Augustine asked him what he was doing.

"I'm emptying the sea into this hole."

"You should know you can't empty the sea into that small hole."

"I have a better chance of emptying the sea than you have of explaining the Trinity."

Yet the Baltimore Catechism shows no indication that the Trinity is difficult to explain. The BC is not a summary of the faith, it is a childish waste of time.
