Once, he happened to be sailing on a ship while pursuing his trading activities. The captain of the ship was not Orthodox, but got into an argument about the Faith with St John. Having been vanquished by the saint's words, the captain resolved to make trouble for him when they got to Belgrade. During the ship's stay at Belgrade, the captain went to the city ruler, a fire-worshipper, and suggested that on his ship was a studious man who also desired to become a fire-worshipper.
The city ruler invited St John to join the fire-worshippers and renounce his faith in Christ.
The saint prayed secretly, calling on the help of Him Who said, "When they shall lead you, and deliver you up, take no thought beforehand what you shall speak, neither do you premeditate; but whatsoever will be given you in that hour, speak that, for it is not you that speaks, but the Holy Spirit" (Mark 13:11). And the Lord gave him the courage and understanding to counter all the claims of the impious and firmly confess himself a Christian. After this, the saint was so fiercely beaten with rods that his entire body was lacerated, and the flesh came off in pieces. The holy martyr thanked God for being found worthy to shed his blood for Him and thereby wash away his sins.
The gathering crowd could not bear this horrible spectacle and they began to shout angrily, denouncing the governor for tormenting a defenseless man. The governor, having the beating stopped, gave orders to tie the Great Martyr to the tail of a wild horse to drag him by the legs through the streets of the city. Residents of the Jewish quarter particularly scoffed at the martyr and threw stones at him. Finally, someone took a sword and cut off his head.
In the morning the vision vanished, but the archer continued to stand motionless. Having told the gathering inhabitants of the city about the vision and what was done to him by the command of God, he was freed from his invisible bonds. Having learned about the occurrence, the ruler gave permission to bury the body of the martyr in the local church. This occurred between the years 1330 and 1340. There is some question about the year of the saint's martyrdom. St Nicodemus of the Holy Mountain gives the year as 1642, while others say it was 1492.
The captain who had betrayed St John repented of his deed, and decided secretly to convey the relics to his own country, but the saint appeared in a dream to the priest of the church, and prevented this. After seventy years the relics were transferred to Sochi, the capital of the Moldo-Valachian principality, and placed in the cathedral church.
In 1685 the Relics of St. John were taken by the Polish King Jan Sobieski to Stryy in Ukraine. They were later transferred to the Basilian Monastery in Zhovkva, also in Halychyna. The Austrian Emperor Joseph II returned them to Suceava in 1783. The Monastery that bears his name was the site of huge pilgrimages on the day of commemorating his martyrdom. Many people came from Bukovyna.
St. John the New is one of the most venerated saints in Moldova, and many miracles are associated with his relics.

Apolytikion for a Martyr in Fourth Tone
Thy Martyr, O Lord, in his courageous contest for Thee received the prize of the crowns of incorruption and life from Thee, our immortal God. For since he possessed Thy strength, he cast down the tyrants and wholly destroyed the demons' strengthless presumption. O Christ God, by his prayers, save our souls, since Thou art merciful.
