Anyone who has fallen into fornication, adultery or any other such bodily impurity, should desist from this revolting filth and cleanse himself through confession, tears, fasting and the like. For God judges unrepentant fornicators and adulterers. He condemns them, dismisses them and consigns them to hell, unquenchable fire and other never-ending punishments, saying, 'Let the impure and accursed be taken away, lest they see and enjoy the glory of the Lord' (cf. Isa. 26:10 LXX).
Gregory PalamasMore Gregory Palamas quotes
Let no one out of laziness or continuous worldly occupations miss these holy Sunday gatherings, which God Himself handed down to us, lest he be justly abandoned by God... If you are detained and do not attend on one occasion, make up for it the next time, bringing yourself to Christ's Church. Otherwise you may remain uncured, suffering from unbelief in your soul because of deeds or words, and failing to approach Christ's surgery to receive... holy healing.
