Hi, my name is Reformed-Calvinist-Christian-Conservative-White-Male-Programmer. What's your name?

Sound strange? It's because as individuals, we don't introduce ourselves by "labels", but by our name.

So why as Christians do we toss the name in favor of the labels?

Are we saved by Luther, that we should be called Lutherans? Was Calvin offered up as a propitiation for our sins, that we should be called Calvinists? Are we through the reformation brought into right standing before God, that we should be firstly identified as reformed?

It's a commonly-criticized aspect of Christianity that the modern Church is so divided --- there are more denominations than most non-Christians care to count, let alone research.

It's not a new problem; this splintering tendency traces all the way back even to the first-century church, when Paul faced it in the Corinthian church he'd helped to plant. The Corinthian believers had somewhere along the way taken to dividing themselves into factions --- missing the point of the church body, and elevating their preferred teachers to undue focus in worship.

For when one says, "I follow Paul," and another, "I follow Apollos," are you not being merely human?
What then is Apollos? What is Paul? Servants through whom you believed, as the Lord assigned to each.
I planted, Apollos watered, but God gave the growth.
So neither he who plants nor he who waters is anything, but only God who gives the growth.
He who plants and he who waters are one, and each will receive his wages according to his labor.
For we are God's fellow workers. You are God's field, God's building. --- 1 Corinthians 3:4-9

Did you catch that? "He who plants and he who waters are one...we are God's fellow workers." So why do we squabble amongst ourselves? Why do we seem to prefer the theologian to God?

You prefer Zwingli to Calvin, or Calvin to Zwingli? Or neither? Do you know why? Labels often serve to obfuscate a lack of knowledge. It is comfortable to call yourself "Presbyterian" if it means you can find others who do the same and never have to worry about challenges of the faith.

Don't hide behind the label! Know what you believe!

And once you know what you believe, as you study the Scripture, you will find that difference in theology should be all the more reason to prefer the name that our ever-true God has given us over the name of one of our fellow errant creatures.

Fear not, for I have redeemed you;
I have called you by name, you are mine....
...I will say to the north, Give up,
and to the south, Do not withhold;
bring my sons from afar
and my daughters from the end of the earth,
everyone who is called by my name,
whom I created for my glory,
whom I formed and made. --- Isaiah 43:1-2, 6-7

The name that God has given us brings security and peace, not ignorance and squabbling.
Let us examine first our top priority --- Christlikeness --- before arguing smaller things, lest we find ourselves like the Corinthian church, to which Paul wrote:

But I, brothers,a could not address you as spiritual people, but as people of the flesh, as infants in Christ.
I fed you with milk, not solid food, for you were not ready for it. And even now you are not yet ready,
for you are still of the flesh. For while there is jealousy and strife among you, are you not of the flesh and behaving only in a human way? --- 1 Corinthians 3:1-4
