As it is not possible to walk without feet or fly without wings, so it is impossible to attain the Kingdom of Heaven without the fulfillment of the commandments.
Theophan the RecluseIf you want to attain salvation, learn and keep in your heart all that the holy Church teaches and, receiving heavenly power from the mysteries of the Church, walk the path of Christ's commandments, under the direction of lawful pastors, and you will undoubtedly attain the Heavenly Kingdom and be saved. All of this is naturally necessary in the matter of salvation, necessary in it entirety and for all. Whoever rejects or neglects any part of it has no salvation.
Theophan the RecluseTo pray is to descend with the mind into the heart, and there to stand before the face of the Lord, ever-present, all seeing, within you.
