Thanks to Chucky, for finding out about the "Miami Christ" on another blog. Catholic apologetics.org quotes verses which state that for the Second Advent, Christ shall return in the clouds, Mark 13:26-27, with his angels Matthew 16:27, and shall do so with obvious signs, Matthew 24:27. Clearly this does not allow for the "Miami Christ" to be the one. He has not demonstrated himself to be the Biblical Christ, with a Biblical return. As well with the Second Advent, Christ shall gather believers as in 1 Thessalonians 4:16-18. This of course has not occurred either! Perhaps Jan Hammer should write a "Miami Christ" theme song.
The website of cult expert Rick Ross describes some of José Luis De Jesús Miranda's theology. I will discuss some of the things mentioned briefly. The site notes that sin is viewed as being abolished, when Jesus died on the cross. Interesting from 1 John 2:2 in the NASB, John states that Jesus was the propitiation (atonement for the wrath of God) for our sins, not for ours only, but the whole world. Earlier in the same book John states in 1:8 that we deceive ourselves if we say we have no sin, and in 1:9 he writes that if we confess our sins God will forgive and cleanse us from unrighteousness. Biblically, Christ has atoned for sin, yet sin still remains presently. Here José Luis De Jesús Miranda, who states he does not read the Bible according to the site, is clearly theologically wrong. Paul mentions also from the NASB in 1 Corinthians 15:43, that the old body was sown in dishonour and weakness, and the new resurrected body shall be raised in glory and power. In verses 15:55-58 Paul makes it clear that sin had been defeated through Christ. Sin has been atoned for by Christ on the cross, and will be completely eliminated in followers at the resurrection.
Concerning José Luis De Jesús Miranda's claim that the Devil does not exist, this is also not in accordance with the Biblical theology. Satan is shown to be thrown into the lake of fire in Revelation, Chapter 20. From the NASB, in 20:10, the Devil is thrown into the lake of fire, and this takes place after the resurrection of believers and the thousand year millennium according to a chronological understanding of Revelation, Chapter 20. It seems clear that Satan will exist after the resurrection of Christians, and since the resurrection and the millennium have not occurred, Satan and his demons still work in our realm.
