Is it true that Christianity is the most divided religion in the world?

We all are familiar with several of the largest denominations of Christianity: the Anglicans, Baptists, Catholics, Lutherans, Methodists, Pentecostals, Presbyterians, etc. Several sources claim that there are approximately 45,000 denominations in Christianity, 200 denominations in the U.S. alone. Do a quick Google search and you'll see what I mean. If this is true, this is certainly astonishing and quite worrying as a Christian. Jesus sincerely desired to unite all believers as one body under God. As you read about His prayer at the Garden of Gethsemane, you could tell that Jesus wouldn't be quite pleased with the massive number of denominations we have today. >**John 17:20-23 (NKJV)** > >20 “I do not pray for these alone, but also for those who will believe in Me through their word; 21 that they all may be one, as You, Father, are in Me, and I in You; **that they also may be one in Us**, that the world may believe that You sent Me. 22 And the glory which You gave Me I have given them, **that they may be one just as We are one**: 23 I in them, and You in Me; **that they may be made perfect in one**, and that the world may know that You have sent Me, and have loved them as You have loved Me. Every denomination differs in terms of doctrine, rituals, eschatology, style of music for worship, Bible translation -- if they are all given the same Bible passage, every one of them will give a different interpretation. Is the Christian community truly so fragmented?
