According to the witness of Church historians, St. Spyridon participated in the sessions of the First Ecumenical Council in the year 325. At the Council, the saint entered into a dispute with a Greek philosopher who was defending the Arian heresy. The plain direct speaking of St. Spyridon showed everyone the impotence of human wisdom before the divine Wisdom: "Listen, philosopher, to what I tell you. There is one God Who created man from dust. He has ordered all things, both visible and invisible, by His Word and His Spirit. The Word is the Son of God, Who came down upon the earth on account of our sins. He was born of a Virgin, He lived among men, and suffered and died for our salvation, and then He arose from the dead, and He has resurrected the human race with Him. We believe that He is One in Essence with the Father, and equal to Him in authority and honor. We believe this without any sly rationalizations, for it is impossible to grasp this mystery by human reason."
As a result of their discussion, the opponent of Christianity became the saint's zealous defender and later accepted holy Baptism. And after his conversation with St. Spyridon, turning towards his companions, the philosopher said: "Listen! Until now my rivals have presented their arguments, and I was able to refute their proofs with other proofs. But instead of proofs from reason, the words of this elder are filled with some sort of special power, and no one can refute them, since it is impossible that man can oppose God. If any of you thinks as I do now, let him believe in Christ and join me in following this man, through whose lips God Himself speaks."
At this Council, St. Spyridon displayed the unity of the Holy Trinity in a remarkable way. He took a brick in his hand and squeezed it. At that instant fire shot up from it, water dripped on the ground, and only dust remained in the hands of the wonderworker. "There was only one brick," St. Spyridon said, "but it was composed of three elements. In the Holy Trinity there are three Persons, but only one God." (
