Okay, sure, it's not polite to call it a catechism, because that would bring up the notion of creeds and formal doctrine, but in reality if you go to just about any church of Christ this is what you will answer with.
(But first, I cannot resist recording a short anecdote of just how much they hate the notion of creeds while ascribing to them in practice. My dad was an elder at one of the biggest CoC in California, perhaps the biggest, when the ministry staff put out a 'What we believe' on the internet. He pointed out that that is a creed, they panicked, and took it down.)
