Origen (185-230AD) speculated on many things. Some of his speculations would later be declared as heresy. The following four points are now known as Origenism.

1. That the souls of men had existed in a previous state, and that their imprisonment in material bodies was a punishment for sins which they had then committed. 
   • He did not believe in reincarnation
2. That the human soul of Christ had also previously existed, and been united to the Divine nature before that incarnation of the Son of God which is related in the Gospels.
3. That our material bodies shall be transformed into absolutely ethereal ones at the resurrection. No physical resurrection.
4. That all men, and even devils, shall be finally restored through the mediation of Christ.

The poem says Cretans lie and say he is dead and the poem says Jupiter is not there.??? "the Cretans are always liars: for thy tomb, o king, the Cretans have reared; and yet thou didst not die, For thou ever livest." Origen says the Cretans do not say Jupiter raised or did not die but his dead there in his tomb. Need to get a full copy of the hymn of Jupiter.

Others have said he also taught: that Christ was subordinate to the Father, and that Christ paid a ransom to Satan.
