“We notice in ourselves the struggle between faith and unbelief, between the good power and the evil one; and in the world, between the spirit of the Church and the spirit of the world. There, through the spirit, you will distinguish two clearly antagonistic sides : the side of light and the side of darkness; of good and evil; the spirit of the Church and of religion, and the spirit of worldliness and unbelief.”

(St John of Kronstadt, ‘My Life in Christ’)
