“Matthew and Thomas, James the son of Alpheus, and Simon called Zelotes,”
Luke 6:15 — Greek Interlinear
Church Fathers on Luke 6:15
When adversaries rose up against the miracles and teaching of Christ, He chose Apostles as defenders and witnesses of the truth, and prefaces their election with prayer; as it is said, And it came to pass, &c.
Let not your ears be open to deceit, that you should think that the Son of God prays from want of strength, that He may obtain what He could not perform; for being Himself the Author of power, the Master of obedience, He leads us by His own example to the precepts of virtue.
Let us examine then in the actions which Jesus did, how He teaches us to be instant in prayer to God, going apart by ourselves, and in secret, no one seeing us; putting aside also our worldly cares, that the mind may be raised up to the height of divine contemplation and this we have marked in the fact, act, that Jesus went into a mountain apart to pray.
