As of this time no man, except Jesus Christ, has been resurrected to immortality. However, the Bible does state that at the resurrection at His Second Coming (I Thes. 4:13-17; I Cor. 15:50-53), the saints of God will be given eternal life.
So let’s explain Matthew 27:52, where we actually find a recorded instance of a multiple resurrection:
“And the graves were opened; and many bodies of the saints which slept arose.”
Notice, that the scripture specifically says their [physical] bodies arose. Further, in verse 53, we see that they appeared unto many. This was a physical resurrection, not a spiritual one. These saints lived out their lives, died again and now await their spiritual resurrection at Jesus Christ’s return, as do all of the saints who have died.
