The following incident took place according to the testimony of Andrei
 Fedorovich Kovalevsky (1840-1901), who was a pious Kharkov landowner who 
pursued asceticism in the field of spiritual literature, and was acquainted with Saint Ioanniki of Svyatogorsk (+ 1882), about whom he wrote the following: 
Once a man of enormous height was brought to [St. Ioanniki], a line Cossack from beyond the Kuban, with a brutally 
distorted face; he was hardly able to be dragged there by two stalwart 
Cossacks, his relatives. The demoniac roared in an inhuman voice, and 
the roar of a bear, and the howl of a wolf, and the grunt of a pig were 
alternately heard in the sounds of his voice, while his eyes sparkled 
with inexpressible malice. 
In the Svyatogorsk Hermitage, in front of the
 cathedral, which stands on a dais, there is a spacious stone staircase 
leading to the platform where the cathedral stands. Having brought the 
possessed man to this staircase, the companions could no longer lead him
 further by any means, about which one of them went to the cathedral to 
inform Father Ioanniki. He himself left the cathedral in the priestly 
stole with the relevant prayer book in his hand and, fearlessly 
approaching the possessed man who was spread on the ground, prepared to 
start reciting the exorcism prayers over him. The possessed man suddenly
 jumped up and, rushing to Father Ioanniki, grabbed him in by the arm 
and, throwing him over his shoulder, ran with him up the stairs around 
the cathedral. The people who were at the same time were frightened and 
did not know what to do: they rushed after the demoniac and saw that 
just opposite the western doors of the cathedral he again fell to the 
ground, while Father Ioanniki sat on him safe and sound and held him by 
the hair. The relatives rushed to tie the hands and feet of the demoniac
 with a rope, but Father Ioanniki forbade them, saying: “Don't touch 
him, leave him alone, he will no longer run; we fought with him and now 
you see who is on top”, - and pointed to the head of the possessed man, 
which he held tightly by the hair. 
Then he got up, covered the possessed
 man with his priestly stole and began to read exorcism prayers over 
him. The possessed man lay still, only breathing heavily, as if about to
 vomit something out of himself; finally, with great effort, he spewed 
out a stinking bloody foam, so stinking that those around him, unable to
 bear the stench, recoiled from him. After that, the possessed man got 
up, began to bow in the direction of the cathedral, entered the 
cathedral itself and prayed earnestly there, and the next day, he 
confessed to Father. 
In confession he explained that he was possessed by
 madness at the time when he dared to inflict beatings on his mother, 
and from then on it had been cruelly tormenting him. With full hope of 
recovery, he set off from the Kuban to this Holy Mountain, having 
received instruction from Father Ioanniki how to behave so as not to 
again be exposed to the actions of an evil spirit. Subsequently, Father 
Ioanniki said, recalling this incident, that when the demoniac threw him
 on his shoulders and carried him up the stairs to the platform around 
the cathedral, he felt in himself some extraordinary power, with which 
he easily overcame the demoniac, noetically invoking the sweetest name 
of the Lord Jesus.
