Tertullian, Against Marcion 37

Salvation comes to Zacchaeus' house as well. On what grounds? Had he perhaps believed that Christ came from Marcion's god? But the blind man's cry still rang in everyone's ears: 'Have mercy on me, Jesus, Son of David,' and the whole crowd was giving praise to God — not Marcion's god, but David's. (Luke 19:9-10) Zacchaeus, for all his foreign blood, may have picked up some scriptural knowledge through Jewish trade connections — more impressively, he fulfilled the prophet's commands even if he never read Isaiah: 'Break your bread for the hungry, and bring the homeless poor into your house' — which he did above all by welcoming the Lord into his home and feeding him — 'and when you see the naked, clothe them' — which he pledged above all by offering half his estate for every work of mercy, tearing up the bonds of predatory contracts, releasing the oppressed, canceling every unjust levy, and declaring, 'If I have extorted anything from anyone, I repay it fourfold.' (Luke 19:9-10) So the Lord says: 'Today salvation has come to this house.' He testified that the Creator's prophet had commanded what brings salvation. (Luke 19:9-10)

When he adds, 'For the Son of Man came to save what was lost,' I no longer waste time arguing that he came to save what was lost, whose it was, and to whom it was lost, since he came to save it. (Luke 19:10; Matthew 18:11) I move the debate to the next level. No one doubts we are talking about a human being. Since a human being consists of two substances — body and soul — the question is: from which substance did the loss occur? If from the body, then the body perished, not the soul. The Son of Man saves what perished: therefore the flesh has salvation too. If the loss came from the soul, the soul's loss is destined for salvation; the flesh, which did not perish, is already safe. If the whole human being perished from both substances, then the whole human being must be saved — and the heretics' verdict denying the flesh's salvation collapses. Now the Christ of the Creator stands confirmed, the one who promised the salvation of the whole human being according to the Creator. (Luke 19:10; Matthew 18:11)

The parable of the servants, judged according to the accounting of the Lord's entrusted money, shows God as judge even on the side of severity — not only demanding a return but taking away what someone merely seemed to have. (Luke 19:9-10) Or if the Creator fabricated this severity too — 'a harsh man, taking what he did not deposit and reaping what he did not sow' — that very line instructs me, since it is his money he teaches me to invest. (Luke 19:9-10)
