What may seem chaos and confusion to you, me and others is not to our Lord and saviour.
We are in times of war, ever since the inquisitions and the infiltration of the Church by the enemies of the cross of Christ.
Jesus is behind this strategy to diversify his body of believers, through many denominations. Offcourse amongst those are also counterfeits, which the Lord knows about too. If we know of Mormons and JWs then the Lord knows those that we don't know like liberals and so forth.
I know it seems overwhelming to contemplate, but Christ is in control of his body. Many ask why so many denominations and the simple answer is the controlling head of the church has strategically through schisms made it that way to make it harder for the infiltrating enemy to subjugate the entire flock under the one ecclesiastical controlling umbrella.
If we look at how Rome is trying to do this with not only Christianity but also the other false religions, it should serve as a warning that two sides are playing. Jesus certainly doesn't want a single mega religiois institution that falls under the one controlling umbrella.
Just to understand the mind of Jesus when the disciples saw others using his name they were compelled to stop them because they were not with their group or denomination, yet Jesus in his strategic mindset said don't do that for if they are not against us, they are for us. We immediately see Jesus here encouraging multiple denominations outside of the 1st century discipleship. This means that since we are at war, the number of denominations is a safe guard to resist the deception of the enemy from within who tries to subjugate the entire congregation within the one controlling umbrella.
