...those called by Christ's name should order their lives. They should persevere in prayers and supplications and, in imitation of the angels, have their eyes lifted up to the Master above the heavens, praising and blessing Him with irreproachable conduct, and waiting for His mystical Coming. As the Psalmist says to Him, 'I will sing and will behave myself wisely in a perfect way. O when wilt Thou come unto me?' (Ps. 101:2).
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.
