If Satan is unable to become incarnate will he possess and control the Antichrist

If Satan is unable to become incarnate will he possess and control the Antichrist?

The short answer is: possibly!

The only inspired books which contain the word "antichrist" are the Epistles of St. John (I, ii. 18, 22, iv. 3; II, 7). As far as we can ascertain, he is the first Christian writer to employ the term. Whether he coined it to express an idea already familiar to his readers under another designation, or found it ready-made in Christian tradition, remains uncertain. Etymologically, in accordance with one meaning of the Greek preposition anti, it denotes an "opponent of Christ." Hence, St. John uses it in the plural, without the article, to characterize certain apostate members of the Christian community (I, ii. 18). In addition, he speaks of the Antichrist, using the noun in the singular with the article to designate an opponent of Christ in the preeminent sense, whose coming at the end of time his readers had been taught to expect.

From the passages referring to Antichrist, par excellence, the Fathers of the Church borrowed the term to designate an individual human adversary of Christ, of unequalled malevolence, who is to come at the end of time. This Patristic doctrine is reaffirmed by practically all the theologians both ancient and modern. The picture which the Fathers draw of Antichrist is based partly upon conjecture, partly upon Jewish apocalyptic literature, partly upon the Scriptures, and partly upon unknown sources. It follows that the only part of their teaching on Antichrist which can lay any claim to our acceptance is that which is derived from the Scriptures. The Biblical interpretations of the Fathers and the theologians are binding only if they are proposed with moral unanimity as pertaining to the deposit of faith or as necessary to guard this deposit. It is difficult, however, to found an argument on the agreement of the Fathers, for they frequently commingle details concerning Antichrist, without stating which particular feature is derived with certainty from Biblical sources.

Modern theologians base their definition of Antichrist on the passages of St. John's Epistles cited above and on the words of St. Paul in II Thess., ii. 1-12. On the authority of these texts they regard it as certain that Antichrist will be an individual human being endowed with the qualities outlined in these texts, who will appear at the end of time and will be destroyed by Christ at His second coming. It is apparent that this explanation of the texts in question does not belong to the deposit of faith and is not necessarily connected with this deposit, for the theologians do not declare that it must be accepted as such; they merely pronounce it as certain. - Antichrist in the Scriptures

Will Satan take possession of the the Antichrist? Like Satan entered the heart of Judas Iscariot? Anything is possible. We can assume that it is a real possibility, but there is definitive teachings on this aspect about the Antichrist. There are interpretations and aspects of Scripture that tend to affirm this possibility.

If one of the Twelve was not be spared from Satan entering into a satanic possession, then perhaps the Antichrist will be possessed also.

Then Satan entered Judas, called Iscariot, one of the Twelve. - Luke 22:3

Some modern leaders such as Hitler were believe to be possessed by Church leaders. I do not this is confined Catholics only. Hitler was really a bad scandral.

Far from being pro-Hitler, the wartime pope Pius XII used to get up in the middle of the night and perform exorcisms on the German dictator, believing him to be possessed by the devil. - Author claims ‘weak’ wartime Pope tried to exorcise Hitler

Thus it is quite possible that the Antichrist will in fact be possessed Satan and his Minions. Time will tell.

Nevertheless, there will always be some who will believe that the Antichrist will be possessed by Satan. He is the one who wishes to deceive the world and be worshipped as God.

Could a mere man resist the final temptation that Christ overcame while he was in the desert? For the final temptation, the Devil took Jesus to a high place, which Matthew explicitly identifies as a very high mountain, where all the kingdoms of the world can be seen and said: **"All these things I will give you if you fall down and do an act of worship to me." Jesus replies "Get away, Satan! It is written: 'You shall worship the Lord your God and only Him shall you serve.'" (Matthew 4: 1-11)

5 The devil led him up to a high place and showed him in an instant all the kingdoms of the world. 6 And he said to him, “I will give you all their authority and splendor; it has been given to me, and I can give it to anyone I want to. 7 If you worship me, it will all be yours.” - Luke 4:1-13

Can the Antichrist resist resist such a temptation as Our Lord did or will he try to worshipped by all of mankind? The Devil has his hands in many things!

Satan, The Beast, and The False Prophet are 3 different personalities that are also the same entity just as The Father, The Son, and The Holy Ghost.

A common tactic of Satan is to imitate or counterfeit the things of God in order to make himself appear to be like God. What is commonly referred to as the “unholy trinity,” described vividly in Revelation 12 and 13, is no exception. The Holy Trinity consists of God the Father, the Son Jesus Christ, and the Holy Spirit. Their counterparts in the unholy trinity are Satan, the Antichrist, and the False Prophet. While the Holy Trinity is characterized by infinite truth, love, and goodness, the unholy trinity portrays the diametrically opposite traits of deception, hatred, and unadulterated evil. - What is the unholy trinity in the end times?

The whole idea of an "indwelling" as opposed to the AntiChrist being literally Satan in the flesh on Earth never made much sense to me. We already know from scripture that Angels can incarnate themselves at will into human bodies, so why would this be any different ? Why would Satan...the one entity in the entire Universe powerful enough to even presume to oppose God need some random human host to proceed with his final and greatest assault ?

Genesis 18:1-19, God and two angels appeared as men and actually ate a meal with Abraham....(Joshua 5:13-14; Mark 16:5), etc
