From the Fathers

"Therefore let us leave untouched the senseless speculations of the masses and the false doctrines, and turn to the teaching delivered to us in the beginning, let us be temperate and ready for our prayers, persevere in fasting, and fervently implore the All-seeing God not to expose us to temptations, since the Lord has said: 'The spirit is willing, but the flesh is weak."

St. Polycarp - Epistle to the Philippians
