4th century mystic John Chrysostom believed that the gifts of the Holy Spirit ceased after the New Testament era.
He also believed in purgatory and taught people to pray for the dead, writing, "Let us help and commemorate them. If Job’s sons were purified by their father’s sacrifice [Job 1:5], why would we doubt that our offerings for the dead bring them some consolation? Let us not hesitate to help those who have died and to offer our prayers for them”.
(Homilies on First Corinthians 41:5) [A.D. 392]
"Weep for those who die in their wealth and who with all their wealth prepared no consolation for their own souls, who had the power to wash away their sins and did not will to do it. Let us weep for them, let us assist them to the extent of our ability, let us think of some assistance for them, small as it may be, yet let us somehow assist them. But how, and in what way? By praying for them and by entreating others to pray for them, by constantly giving alms to the poor on their behalf. Not in vain was it decreed by the apostles that in the awesome mysteries remembrance should be made of the departed. They knew that here there was much gain for them, much benefit. When the entire people stands with hands uplifted, a priestly assembly, and that awesome sacrificial Victim is laid out, how, when we are calling upon God, should we not succeed in their defense? But this is done for those who have departed in the faith, while even the catechumens are not reckoned as worthy of this consolation, but are deprived of every means of assistance except one. And what is that? We may give alms to the poor on their behalf”.
(Homilies on Philippians 3:9”“10) [A.D. 402]
Furthermore, he believed that the communion bread and wine became the body and blood of Jesus when consecrated. He wrote that no one can partake of Christ or be saved outside the Church and faith thereof (which foreshadows Catholicism).
Incredibly, he railed against those who abstained from alcohol, and encouraged violence against blasphemers: "Paul is not ashamed, and does not blush, after the many and great signs which he had displayed even by a simple word; yet, in writing to Timothy, to bid him take refuge in the healing virtue of wine drinking. Not that to drink wine is shameful. God forbid! For such precepts belong to heretic … But since our discourse has now turned to the subject of blasphemy, I desire to ask one favor of you all, in return for this my address, and speaking with you; which is, that you will correct on my behalf the blasphemers of this city [i.e., blaspheming against God by saying that wine is evil] And should you hear anyone in the public thoroughfare, or in the midst of the forum, blaspheming God; go up to him and rebuke him; and should it be necessary to inflict blows, spare not to do so. Smite him on the face; strike his mouth; sanctify your hand with the blow, and if any should accuse you, and drag you to the place of justice, follow them thither; and when the judge on the bench calls you to account, say boldly that the man blasphemed the King of angels! For if it be necessary to punish those who blaspheme an earthly king, much more so those who insult God.” (Homilies on the Statues 1,7)
Lastly, John Chrysostom was terribly anti-Semitic, comparing, in his Adversus Judaeos (Against the Jews) homily, the synagogue to a pagan temple, representing it as the source of all vices and heresies. He described it as a place worse than a brothel and a drinking shop; it was a den of scoundrels, the repair of wild beasts, a temple of demons, the refuge of brigands and debauchees, and the cavern of devils, a criminal assembly of the assassins of Christ. Chrysostom hated both the synagogue and the Jews, saying that demons dwell in the synagogue and also in the souls of the Jews, and describing them as growing fit for slaughter. The Nazis quoted him (and Martin Luther) during the Holocaust.
Again, I do not look to (wrongly) celebrated men, but to the Word of God.
