Mark 15:21

Christ, moreover, he affirms to have been sent, not by this maker of the world, but by the above-named Abraxas; and to have come in a phantasm, and been destitute of the substance of flesh: that it was not He who suffered among the Jews, but that Simon was crucified in His stead: whence, again, there must be no believing on him who was crucified, lest one confess to having believed on Simon.

Now that you may understand what is the difference between statements which are diverse and contradictory, one of the evangelists has stated that Christ carried the cross, another that Simon the Cyrenian carried it: but this causes no contradiction or strife. "And how," you say, "is there no contradiction between the statements that he carried and did not carry?" Because both took place. When they went out of the Praetorium Christ was carrying it: but as they proceeded Simon took it from Him and bore it.

This is well signified by that Simon who, found on the road, carries the Lord's cross under compulsion. For burdens belonging to another are carried under compulsion when something is done through the pursuit of vanity. Who then are designated by Simon, if not the abstinent and arrogant? They indeed afflict the flesh through abstinence, but they do not seek the fruit of abstinence within. Therefore Simon carries the Lord's cross under compulsion, because when he is not led to a good work by good will, a sinner performs the deed of a just man without fruit. Hence the same Simon carries the cross but does not die, because the abstinent and arrogant indeed afflict the body through abstinence, but through the desire for glory they live to the world.

Firstly, it was carried by the Lord, and then it was imposed on Simon, whom they happened to meet as they were going out. And this is in a fitting order of mystery. For he undoubtedly suffered for us, leaving us an example that we might follow in his footsteps.

And because this Simon is said to be not from Jerusalem but a Cyrenian (for Cyrene is a city of Libya, as we read in the Acts of the Apostles), it is rightly by him that the peoples of the Gentiles are designated, who once were strangers and foreigners to the covenants, now by obeying are citizens and household members of God, and, as it is said elsewhere, heirs indeed of God, but co-heirs of Christ (Romans VIII). Thus fittingly Simon the obedient, Cyrene, is interpreted as heir. And it should not be overlooked that the same Simon is reported to have come from the country. The country in Greek is called πάγος. From this, we call pagans those whom we see as alien to the city of God and almost devoid of urban conversation. But Simon, coming out of the country, carries the cross after Jesus, as the people of the nations, having abandoned pagan rites, obediently embrace the footsteps of the Lord's passion.

(ubi sup.) Or, since this Simon is not called a man of Jerusalem, but a Cyrenian, (for Cyrene is a city of Libya,) fitly is he taken to mean the nations of the Gentiles, which were once foreigners and strangers to the covenants, but now by obedience are heirs of God, and joint heirs with Christ. Whence also Simon is fitly interpreted 'obedient,' and Cyrene 'an heir.' But he is said to come from a country place, for a country place is called 'pagos' in Greek, wherefore those whom we see to be aliens from the city of God, we call pagans. Simon then coming out from the country carries the cross after Jesus, when the Gentile nations leaving pagan rites embrace obediently the footsteps of our Lord's Passion.

These servants of the devil compelled, as it is said, a certain man to carry His cross; meanwhile, another evangelist says that Jesus went out, bearing the cross Himself (Jn. 19:17). But both things happened: at first He Himself carried the wood of the cross for some time, and when they found another able to carry it, they compelled this latter man, and the cross was borne by him. And why is it also mentioned whose father this man was? For greater confirmation, because that man was probably still alive and could recount everything concerning the cross. Let us also become "Simon," which means obedience, and take up the cross of Jesus, "mortifying our members which are upon the earth" (Col. 3:5).

Now John says that He Himself bare His cross, for both took place; for He first bore the cross Himself, until some one passed, whom they compelled, and who then carried it. But he mentioned the name of his sons, to make it more credible and the affirmation stronger, for the man still lived to relate all that had happened about the cross.

And they compel Simon a Cyrenian, who passed by, coming out of the country, the father of Alexander and Rufus, to bear his cross.

Now since some men are known by the merits of their fathers, and some by those of their sons, this Simon, who was compelled to carry the cross, is made known by the merits of his sons, who were disciples. By this we are reminded, that in this life, parents are assisted by the wisdom and the merits of their children, wherefore the Jewish people is always held worthy of being remembered on account of the merits of the Patriarchs, Prophets, and Apostles. But this Simon who carries the cross, because he is compelled, is the man who labours for human praise. For men compel him to work, when the fear and love of God could not compel him.
