There is an opinion that the name Vadim is rooted in the Old Russian language or was derived from the Slavic Vadimir. However, the name Vadim was already used in ancient Persia, and a saint with this name is captured in the church calendar.
Men named Vadim were not left without their Orthodox heavenly patron, since the Church venerates the Monk Martyr Vadim of Persia in the face of saints. This saint had the rank of archimandrite (he was the head of a men's monastery) and lived in the 4th century in Persia, therefore the church saints call this ascetic Persian. Memorial Day of Saint Vadim of Persia is celebrated on April 22nd. This is the date of the name day of all Vadims.
From the life of the saint it is known that the righteous man spent his life in the city of Bethlapat during the reign of the Persian state by King Sapor. In the 4th century AD, the Persians worshiped the sun and fire, being followers of the religion of Zoroastrianism. Vadim chose a different faith for himself - he became a Christian and was looking for a solitary, ascetic life. This prompted the righteous to erect a monastery outside the city, in which Vadim later became an archimandrite.
Tsar Sapor, having learned about the religion of Vadim, decided to imprison the saint in prison. At that time in Persia, all Christians who were known or reported to the king were tortured. Together with Vadim, a certain Nirsan was imprisoned in prison. In addition to imprisonment, the holy Christians were subjected to various tortures. Nirsan could not adequately endure physical suffering and eventually denied Jesus Christ. As proof of the veracity of the renunciation, the tsar commanded Nirsan to chop off Saint Vadim's head with his own hand with a sword. Nirsan, after conscientious hesitation, agreed and killed the archimandrite. This happened in 367.
The death of the holy righteous man tormented Nirsan for a long time. Remorse led the killer to despair, which resulted in the latter's suicide.
