St. Anastasius of Sinai: True Christianity Requires Both Faith and Works

What the video says

The speaker defines a true Christian as a dwelling place of Christ held together by both correct belief and good works, citing Jesus' words that those who love Him keep His words and become God's home. Faith without works is dead, as are works without faith, and one must keep clean from foul deeds lest the devil enter the soul like a thief.

The devil recognizes whether Christ dwells in a person by observing anger, oaths, foul language, condemnation, hatred, injustice, conceit, boasting, excessive laughter, lack of habitual prayer, and failure to remember death. Scripture from Deuteronomy, David, Isaiah, Solomon, and Sirach consistently teaches that God requires fear, love, obedience, hatred of evil, and justice for the vulnerable, while rejecting vain worship and hypocrisy.

The Apostolic Constitutions and St. Gregory of Nyssa warn that calling God "Father" with an unclean conscience insults God and invokes the devil instead, since light has no fellowship with darkness and a good tree cannot bear evil fruit. St. Cyril of Jerusalem and St. John Chrysostom affirm that the name "Christian" and the prayer "Our Father" demand a corresponding life of justice, purity, and truth, for one cannot serve both God and mammon.

St. Basil the Great and the Apostle teach that whoever commits sin becomes sin's servant and the devil's child, while faith without works is dead like a body without spirit. St. John Chrysostom on fasting and prayer insists that defiled hands (theft, evil actions) and defiled mouth (blasphemy, abuse, insult) prevent prayer from ascending, requiring cleansing through weeping, alms, confession, and reconciliation before approaching God.

St. John Chrysostom, St. John of the Ladder, Mark the Monk, and Maximus the Monk all warn that faith without matching life is useless, like a face without eyes or water poured into a leaky vessel, and that true Christian wisdom pursues commandments to free the mind from passions, dogma to know truth, and faith to contemplate the Holy Trinity.
