From Pope Benedict’s General Audience of about a year ago:
A first fact strikes one based on these references: Jesus does not exclude anyone from his friendship. Indeed, precisely while he is at table in the home of Matthew-Levi, in response to those who expressed shock at the fact that he associated with people who had so little to recommend them, he made the important statement: “Those who are well have no need of a physician, but those who are sick; I came not to call the righteous, but sinners” (Mk 2: 17).
The good news of the Gospel consists precisely in this: offering God’s grace to the sinner!
Elsewhere, with the famous words of the Pharisee and the publican who went up to the Temple to pray, Jesus actually indicates an anonymous tax collector as an appreciated example of humble trust in divine mercy: while the Pharisee is boasting of his own moral perfection, the “tax collector… would not even lift up his eyes to heaven, but beat his breast, saying, “God, be merciful to me a sinner!'”.
And Jesus comments: “I tell you, this man went down to his house justified rather than the other; for every one who exalts himself will be humbled, but he who humbles himself will be exalted” (Lk 18: 13-14).
Thus, in the figure of Matthew, the Gospels present to us a true and proper paradox: those who seem to be the farthest from holiness can even become a model of the acceptance of God’s mercy and offer a glimpse of its marvellous effects in their own lives.
St John Chrysostom makes an important point in this regard: he notes that only in the account of certain calls is the work of those concerned mentioned. Peter, Andrew, James and John are called while they are fishing, while Matthew, while he is collecting tithes.
These are unimportant jobs, Chrysostom comments, “because there is nothing more despicable than the tax collector, and nothing more common than fishing” (In Matth. Hom.: PL 57, 363). Jesus’ call, therefore, also reaches people of a low social class while they go about their ordinary work.
Another reflection prompted by the Gospel narrative is that Matthew responds instantly to Jesus’ call: “he rose and followed him”. The brevity of the sentence clearly highlights Matthew’s readiness in responding to the call. For him it meant leaving everything, especially what guaranteed him a reliable source of income, even if it was often unfair and dishonourable. Evidently, Matthew understood that familiarity with Jesus did not permit him to pursue activities of which God disapproved.
The application to the present day is easy to see: it is not permissible today either to be attached to things that are incompatible with the following of Jesus, as is the case with riches dishonestly achieved.
Jesus once said, mincing no words: “If you would be perfect, go, sell what you possess and give to the poor, and you will have treasure in heaven; and come, follow me” (Mt 19: 21).
This is exactly what Matthew did: he rose and followed him! In this “he rose”, it is legitimate to read detachment from a sinful situation and at the same time, a conscious attachment to a new, upright life in communion with Jesus.
