The church is just a name for all restored to pre fallen nature condition. All on earth are descendants of Adam. It does not matter who or what parents were there or where, at certain times. It is not about ethnicity nor even any belief system. There are two general body resurrections. They are considered body resurrections because it brought those as one group from one state of existence to another one.
The first one happened when Jesus said on the cross, "It is finished." This was the last day for the OT saints. All in Christ from Adam to Lazarus would be taken out of sheol, and it was done as one resurrection. They walked the streets for 3.5 days. Then with Jesus Christ as their Shepherd, they all ascended to Paradise as one group.
The second resurrection as one body is at the first day of the 1000 year reign of Christ. The harvest of the Trumpets and Thunders where the sheep and wheat was harvested produced dead once again in the dust. Then there were those beheaded who did not take the mark 666. This group of people will be resurrected to live on the earth for 1000 years. They have new bodies, but not the same as the church. They have the ability to have more children. They will not be judged as sinners at the GWT, but they do not have glorified bodies yet.
The dead before the GWT at the end are not resurrected. They are not given new bodies. They are sent to the lake of fire. Now if there is a resurrection then, it will be God's knowledge only. We are not told specific details. God is Sovereign and can save whom He pleases at the last hour. Those who labored for God all their life, can not be bitter nor negate the state of souls who only lived one hour for God.
There is one more group considered resurrected, but it is not bodily, nor in one group. The church age does not have a bodily resurrection. Paul has been misunderstood for the last 1900 years. In this age the soul does not have to go to sheol at all. That was the only need for a resurrection. We do not go to sheol. We will not be resurrected from sheol. Never, no intermediate, get more better, stomping ground. Paul clarified by stating, "Absent from the body, present with the Lord." Every time a person in Christ dies they are "resurrected". They rise first, before the living. It is not a mystery, we shall not all sleep. But not even those in Paradise, currently have glorified bodies. The OT had to wait until Christ to enter Paradise. The whole church and OT saints have to wait until the 5th and 6th seal to receive their glorified bodies. Then and only then will humanity be restored to Adam's original condition. Physical and spiritual reality will be restored as one complete physical state like God created in Genesis 1. We will all understand what the creation was at the 6th seal.
