Heb 13:13

“The Lord Redeemer very rightly commanded whoever would follow Him to strip himself and leave the world; for a man ought first to cast off from himself the causes of slackness, and then approach the work. When the Lord Himself began to wage war with the devil, He fought him in the arid desert. Paul also exhorts those who take up the cross of Christ to go forth from the city, saying: "Let us go forth unto Him without the city and take up His reproach, for He suffered without the city." For by setting himself apart from the world and what pertains to it, a man speedily forgets his former habits and his mode of life and he will not struggle long with these. But if he should draw near to the world and its possessions, he will speedily enfeeble the strength of his mind. Wherefore one must know that separation from the world greatly aids a man and guides him on the way of progress in the fierce and saving struggle. It is proper, then, and helpful in this struggle if a monk's cell be in a poor and mean condition, and if his cell be empty and devoid of everything that could incite in him the desire of ease. For when the causes of slackness are distant from a man, he is not endangered by the twofold warfare, that is, the one which is both inward and outward. See how much easier is the struggle when a man desires things that are afar off than when the very things themselves are close at hand and by their sight inflame the thoughts; for the struggle in the latter case is twofold.”

“Since Jesus Christ suffered outside the gates, let us also go out to Him outside the gates, that is, let us be outside the world, "bearing His reproach," enduring the same sufferings. He, as one condemned and a robber, was crucified outside; let us also not be ashamed to withdraw from the world and from its luxury, even if this should seem dishonorable. Again he persuades them to endure the insults inflicted on them by the Jews, or the plundering.”

“Then when he says, Therefore let us go forth to him, he draws two conclusions. In regard to the first he says: Therefore, we have said that we have an altar outside the camp. Hence, we must do two things: namely, go to it and sacrifice upon it. He tells how to go when he says that Jesus Christ suffered and bore the reproach of His passion outside the gate; therefore, let us go forth to him outside the camp, i.e., outside the general community of carnal things, or outside the observances of the Law, or outside the senses of the body, bearing abuse for him, i.e., for Christ, i.e., the signs of Christ's passion by which Christ became a disgrace among men and offscouring of people: 'My heart has expected reproach and misery' (Ps. 68:21). Or bearing abuse for him, i.e., let us reject the ceremonies of the Law, now that that truth has come, on account of which we are a reproach among the Jews, i.e., on account of the signs of penance, which are reproved by carnal men: 'Esteeming the reproach greater riches than the treasures of the Egyptians' (Heb. 11:26). For just as Christ was accused of undermining the Law, so the apostles were reproached for preaching that the ceremonies of the Law should not be observed: 'And I brethren, if I yet preach the circumcision, why do I yet suffer persecution' (Gal. 5:11).”

“"Let us then go to him outside." Since Christ suffered outside the gate, let us go out to Him outside the camp, that is, outside the world, bearing nothing worldly, neither earthly nor carrying the filth of the earth. This, outside the gate, that is, outside the world, bearing His reproach, that is, suffering the same things as He did, if He should ask; for this indicates, bearing the reproach he endured, which He Himself endured through both the mockeries and the scorn.”
