Catena Aurea · Markusevangelium 11
And when they came nigh to Jerusalem, unto Bethphage and Bethany, at the mount of Olives, he sendeth forth two of his disciples, And saith unto them, Go your way into the village over against you: and as soon as ye be entered into it, ye shall find a colt tied, whereon never man sat; loose him, and bring him. And if any man say unto you, Why do ye this? say ye that the Lord hath need of him; and straightway he will send him hither. And they went their way, and found the colt tied by the door without in a place where two ways met; and they loose him. And certain of them that stood there said unto them, What do ye, loosing the colt? And they said unto them even as Jesus had commanded: and they let them go. And they brought the colt to Jesus, and cast their garments on him; and he sat upon him. And many spread their garments in the way: and others cut down branches off the trees, and strawed them in the way. And they that went before, and they that followed, cried, saying, Hosanna; Blessed is he that cometh in the name of the Lord: Blessed be the kingdom of our father David, that cometh in the name of the Lord: Hosanna in the highest.
(in Luc. 9, 6) Or else, they found it bound before the door, because whosoever is not in Christ is without, in the way; but he who is in Christ, is not without. He has added in the way, or in a place where two ways meet, where there is no certain possession for any man, nor stall, nor food, nor stable; miserable is his service, whose rights are unfixed; for he who has not the one Master, has many. Strangers bind him that they may possess him, Christ looses him in order to keep him, for He knows that gifts are stronger ties than bonds.
