Unity in the church

Is there a solution for the conflict in the unity appeals in Paul's letters, like 1 Corinthians 1:10 and the divisions in the church--not only THE church, but our local church congregation? It's not much comfort to see the local churches of the first century were very divided on many issues. Even if read in context about who baptized whom, Paul confirms the message in other letters. But in the 21st century, it is no better and Christians have had 2000 years to get it right.

The abortion conflict really does not allow for "unity." And we are at least a decade or two behind grappling with the genetic manipulation problem that technology has wrought. But the abortion/race/climate/border/gender factions are keeping us putting out fires so we don't have the energy or time to work together on other issues. If we can't agree that a 9 month old baby in the womb is a "life" worthy of protection, we're certainly not prepared to deal with designer babies, or using body parts of aborted babies to correct defects.

I can not pray for unity with people who say conservatives are perverse and obsessed with sex when they destroy life and believe the sexual abuse of trans surgery is OK.

When the U.S. has enough fuel to keep others from starving and we're asked to have unity on Biden's death policies, I just see no good in that.

Running drugs and sex trafficking when it could be stopped but Christians fight each other on what to do and take government grants to assist, is serving God how?

That's defiling the whole concept of unity in Christ. Maybe mercy. Yes, I can ask for God's mercy and grace for all of us. When I read of David's battles, I don't see him asking for unity with those who defy God's will.
