Luke 10:33

Now this Samaritan was also coming down. For who is he that ascended upon into heaven, but he who came down from heaven, even the Son of Man who is in heaven (John 3:13.).

Now when He came He was made very near to us by His taking upon Himself our infirmities, He became a neighbour by bestowing compassion. Hence it follows, And when he saw him he was moved with compassion.

(ubi sup.) A Samaritan coming by, far removed by birth, very near in compassion, acted as follows, But a certain Samaritan as he journeyed came where he was, &c. In whom our Lord Jesus Christ would have Himself typified. For Samaritan is interpreted to be keeper, and it is said of him, He shall not slumber nor sleep who keeps Israel; (Ps. 128:4.) since being raised from the dead he dieth no more. (Rom. 6:9.) Lastly, when it was said to him, Thou art a Samaritan, and hast a devil, (John 8:48.) He said He had not a devil, for He knew Himself to be the caster out of devils, He did not deny that He was the keeper of the weak. He came in the likeness of sinful flesh, therefore 1 near to him, as it were, in likeness. (Serm. 171.) For what so distant, what so far removed, as God from man, the immortal from the mortal, the just from sinners, not in distance of place, but of likeness. Since then He had in Him two good things, righteousness and immortality, and we two evils, that is unrighteousness, and mortality, if He had taken upon Him both our evils He would have been our equal, and with us have had need of a deliverer. That He might be then not what we are, but near us, He was made not a sinner, as thou art, but mortal like unto thee. By taking upon Himself punishment, not taking upon Himself guilt, He destroyed both the punishment and the guilt.

But He says, journeying, as though He purposely determined this in order to cure us.

(Severus.) Now Christ here fully calls Himself a Samaritan. For in addressing the lawyer who was glorying in the Law, He wished to express that neither Priest nor Levite, nor all they who were conversant with the Law, fulfilled the requirements of the Law, but He came to accomplish the ordinances of the Law. Or He came by the way. For He was a true traveller, not a wanderer; and came down to the earth for our sakes.
