Who does this? What does this look like?
I see how far our faith has been "drifting" away from it's roots
Yes for sure. The heresy of Protestantism has drifted from Christ's command to be 'one' in our beliefs
The Church of the apostles was definitely one: "There is one body and one spirit," Paul wrote, "just as you were called to the one hope that belongs to your call, one Lord, one faith, one baptism, one God and Father of us all" (Eph. 4:4-5). Paul linked this primitive unity to the Church's common Eucharistic bread: "Because there is one bread, we who are many are one body, for we all partake of one bread" (1 Cor. 10:17). Jesus had promised at the outset that "there would be one flock, one shepherd" (John 10:16).

The heresy of Protestantism is just a microcosm of the massive heresy of sungod worship known as the catholic church.
Yeshua gave us no ‘church.’
The church is man made heresy from top to bottom. It is a usurpation of the authority of Yehova’s apostles, and ruthless nicolaitan tyranny over his sheep.
Paul rebuked error in the early church so they were already not one by your definition. In addition Christ never told us to embrace error or heresy for the sake of unity. The Roman church was in error and rather than relenting they doubled down resulting in the Reformation. Luther wanted to weedout error in the Roman church not split from it. 500 years later we have come full circle with the Roman church again doubling down on error and frankly heresy/apostasy. Have they learned the lesson? I doubt it.
However God brought great blessing out of the Reformation. Uncounted millions now understand they are saved by Grace through faith in Jesus - the incredible gift of God- instead of being trapped In the teaching of works based salvation that no one could ever achieve.
