We all know the phrase “practice what you preach.”  It’s a way to call someone a hypocrite, and at the same time tear down what the other person claims to believe in.  These beliefs may be political or moral philosophies, but they may also be religious beliefs like denominations or theological systems.  For this post, I’ll call all of these “isms.”

The history of Christianity has been a constant conflict between and competition among different “isms.”  Catholicism, Lutheranism, Calvinism, Methodism, and others.  Even the ones that don’t use the actual letters “ism” at the end are still “isms.”  So much of being a Christian involves figuring out which “ism” we belong to, and also figuring out what’s wrong with the other “isms.”  I see this no more clearly than on social media, where the competing camps are so clearly identified, and people write others off for being in the wrong camp.

We put a lot of time and effort into being as good at our chosen “ism” as we can.  If we can go with the flow according to that “ism,” we can feel like we are pretty good Christians.  We may be able to do a decent job at following the “ism” that we preach, and in many cases following our “isms” isn’t a bad thing.  All denominations have their pros and cons, and they often attract people with similar strengths and weaknesses.

But as we seek to be the best at our “ism” that we can be, are we practicing Christianity?  Jesus confronts us with this in Matthew 19:17 – “And he said to him, ‘Why do you ask me about what is good? There is only one who is good. If you would enter life, keep the commandments.’”

We may think of our “isms” as varieties or types of Christianity, and in a cultural way they are.  However, in God’s eyes there aren’t different types of Christianity.  There is only one Christianity – the life that Christ lived is the only practice of Christianity that will ever be good enough.  Even if I perfectly practice what I preach as a Presbyterian or Baptist, for instance, I’ll still fall far short of God’s standard for “good.”

“Isms” are unavoidable in this world, and they often point us in the right direction, but they don’t get us all of the way there.  We seek to please God as we best know how, but none of our “isms” are enough.  They aren’t enough to save us, and they’re also too much for us to perfectly practice what we preach.  We can’t meet our own, lowered, standards.

This is why the apostle Paul wrote “For I decided to know nothing among you except Jesus Christ and him crucified” in 1 Corinthians 2:2.

Preaching Christ crucified is the only thing we can preach that was ever practiced perfectly, because it wasn’t practiced by us.  It was practiced by the only One who was ever perfect, and it’s better than all of our “isms.”
