How will the Body of Christ be raptured?

Throughout the epistles of Paul, the Body of Christ is illustrated as a 'mystery'. Though this agency was always part of God's great redemption plan, it only came about through the ministry of Paul and due to the unbelief of Israel, who, through the Old Testament and the Gospels, was the vehicle of God to bring salvation unto the Gentiles. The Body of Christ, and salvation for the Gentiles through Israel's fall, was never prophesied in the Bible and it is why Paul refers to this Grace program as a mystery. 

It is this very point of 'mystery' that brings me to the conviction that the catching away of the Body of Christ will be silent, without any visible and audible signs in the earth, with no trumpet blasts, no graves being opened and the dead rising up to meet the Lord in the clouds, according to 1 Thessalonians 4:16-17. Our rapture will be uneventful and in secret and will be the primary instigator of confusion amongst unbelievers, contributing to delusions and false beliefs.

Phil.3:20-21 For our conversation [citizenship] is in heaven; from whence also we look for the Saviour, the Lord Jesus Christ: 21 Who shall change [instantaneously] our vile body, that it may be fashioned like unto his glorious body, according to the working whereby he is able even to subdue all things unto himself.

We look for our Saviour from this heavenly position, not like his disciples, and Israel, who will be looking for Him in the clouds according to Act.1:9-11. The above verse also clarifies that our 'vile bodies' will be changed, in a moment, or instantaneously, in the context of 1 Cor.15:52, into glorified bodies at this event.

So, based on the image above, the Body of Christ will be silently raptured, instantaneously translated into heaven, as part of the first phase of the multi-part return of Christ. 1 Thessalonians 4:16-17 is a sequence of events that spans from before the tribulation, our rapture, and culminates at the end of the tribulation with His appearing in the clouds and the resurrection and rapture of saints into the air when he a comes as King and Conqueror at the second advent.
