Millenarianism is the bread and butter of fundamentalist interpretation - post, pre, whatever. The Rapture, again, pre-trib, mid-trib, post-trib, etc. The Catholic Church unequivocally rejects both of these theologies.
If the denominations are arguing over how to worship, they're arguing over matters of tradition, which should scandalize all Protestants since that was the crux of the break with Rome back at the Reformation.
Where we differ is on the non essentials
So Protestants continue to reject Christ's prayer for unity within His flock over "non-essential" issues? I would not want to be accountable for that before God.
>Dispensationalist, premillenialists, postmillenialists, evangelicals, 7th-Day adventisits, Jehova's Witnesses, for starters all have different ideas of Revelation.<
Again your ignorance is showing.Dispensationalist, premillenialists, postmillenialists, evangelicals are not denominations.I infact Evangelicals within the same denomination are proponents of all of the ..ists.None of which effect salvation.Jehova's Witnesses are a cult and are not Christian because they deny the Divinity of Jesus Christ.

We are unified at the base of the cross.I could care less wheather you refuse to be sprinkled rather than partaking of Biblical Baptism.(If you believe on the Lord Jesus Christ you are in his kingdom)I could care less if you sing the notes I prefer instruments.I could care less wheather you beliebve in election or free will all that matters is you believe on the Son of God.
The biggest impediment to Unity in Christianity is the refusal of Roman Catholics to take Communion with the rest of Christianity.We accept your testimony that you know the Lord and will allow you to sit at our communion table any day if you know Jesus.
