Protestants have so many denominations cant they figure it out - be one Church?

So many denominations cant Protestants figure it out, and be one Church?

A: We are one Church; the Bride of Christ, the body of Christ. 

 Just because certian other ones claim to be The Church doesnt make it so. Theyre false religions masqurading as Christianity (such as RCC, Orthodox & the Cults).

History shows the truth. 

Protestantism [the only "Christianity" now] is "united in the Gospel" (called the essential or primary) is the salvific main issue of Christianity. The 'secondary' issues are things folk learn and grow to understand as they learn more. They can come to a more accurate understanding in time on things such as end times views. That only happens if they themselves study the Word. A lot of professing believers arent, so they remain ignorant. 

"Denominations" [again, speaking of protestant] came about from the ☆Reformation era☆ when the Church was being reclaimed/restored to God's truth; as revealed in the 66 books of Holy Scripture; God's Wird to mankind.

Where were those people? Those who taught truth? -> diff EU countries. Thus some heard from Wesley and some Luther and others Calvin. So they followed not just the Gospel [that they all preached rightly], but in the secondary areas they taught 'as they understood' as they studied (and if had any access to anything historical from history in those tumultuous days) they preached/taught what they came to know. Thus....there were diff 'secondary' understandings. Most of the Reformed Fathers were killed by RCC so they didnt finish studying nor have long to teach the people. Thus those few faithful believers (who were basically in underground churches) held to what was taught by each of those men depending in where those people lived. And as they fled persecution they also ended up in diff countries thus Lutheranism, Reformed, Baptist, etc denoms exist. The refirmers never intended denominations to form, but with disagreements in sime areas, God allowed or directed diff denominations to exist [perhaps as a stumbling block for unsaved mockers?].  

The only problem those believers had back then was they stayed in those teachers circles, denominations emerged. And it was still apprenticeship era where pastors raised up other leaders/pastors in that church. They only studied what that original reformed leader taught (became denomination teaching). They never kept reforming or theyd have a more accurate understanding of Scripture. More biblically accurate churches are around today. Those who study Scripture can decide to leave their denom for a more accurate one. Many do. 

Keep in mind in EU/UK the Christian denomination was controlled by the State (nation), whatever they adopted was the one they all had to follow and laws required everyone to be in church on Sunday. So whether that was a false Church (RCC), a mixed bag (COE) or Protestant one... they didnt have freedom to go to a diff one. Didn't even know another one existed, nor know anything else other than what they were allowed (for Christian ones im talking on the secondary matters). Many couldn't afford Bible so there's that too. God still saves and people still obey the Gospel. If their faith is weak, theyre still Redeemed and Heavenbound. They'll have perfect knowledge when they get there 😊

So you have to have a understanding of church history. You can't look at things thru a USA lense with a modern view, you need a fuller understanding for the WHY and how we got here today. US has freedom [orig: Freedom within Christianity; any denomination, not a nationally dictated one (like UK)]. Freedom in Christianity didnt exist in other countries, and today now it has a bit because of US influence. However since 2026 it has been squashed globally (incl EU) with WEF/NWO Islam agenda being pushed. 

YHWH is still in control.
