From: Matthew 5:33-37

Jesus and His Teaching, the Fulfillment of the Law (Continuation)

(Jesus said to His disciples,) [33] “Again you have heard that it was said to the
men of old, ‘You shall not swear falsely, but shall perform to the Lord what you
have sworn.’ [34] But I say to you, Do not swear at all, either by Heaven, for it is
the throne of God, [35] or by the earth, for it is His footstool, or by Jerusalem, for
it is the city of the great King. [36] And do not swear by your head, for you can-
not make one hair white or black. [37] Let what you say be simply, ‘yes’ or ‘no’;
anything more than this comes from evil.”

Commentary:

33-37. The Law of Moses absolutely prohibited perjury or violation of oaths (Exo-
dus 20:7; Numbers 30:3; Deuteronomy 23:22). In Christ’s time, the making of
sworn statements was so frequent and the casuistry surrounding them so intri-
cate that the practice was being grossly abused. Some rabbinical documents
of the time show that oaths were taken for quite unimportant reasons. Parallel
to this abuse of oath-taking there arose no less ridiculous abuses to justify non-
fulfillment of oaths. All this meant great disrespect for the name of God. How-
ever, we do know from Sacred Scripture that oath-taking is lawful and good in
certain circumstances: “If you swear, ‘As the Lord lives’, in truth, in justice, and
in uprightness, then nations shall bless themselves in Him, and in Him shall
they glory (Jeremiah 4:2).

Jesus here lays down the criterion which His disciples must apply in this connec-
tion. It is based on re-establishing, among married people, mutual trust, nobility
and sincerity. The devil is “the father of lies” (John 8:44). Therefore, Christ’s
Church must teach that human relationships cannot be based on deceit and in-
sincerity. God is truth, and the children of the Kingdom must, therefore, base
mutual relationships on truth. Jesus concludes by praising sincerity. Throughout
His teaching He identifies hypocrisy as one of the main vices to be combatted
(cf., e.g., Matthew 23:13-32), and sincerity as one of the finest virtues (cf. John
1:47).

First reading	2 Corinthians 5:14-21 ©

The love of Christ overwhelms us when we reflect that if one man has died for all, then all men should be dead; and the reason he died for all was so that living men should live no longer for themselves, but for him who died and was raised to life for them.

From now onwards, therefore, we do not judge anyone by the standards of the flesh. Even if we did once know Christ in the flesh, that is not how we know him now. And for anyone who is in Christ, there is a new creation; the old creation has gone, and now the new one is here. It is all God’s work. It was God who reconciled us to himself through Christ and gave us the work of handing on this reconciliation. In other words, God in Christ was reconciling the world to himself, not holding men’s faults against them, and he has entrusted to us the news that they are reconciled. So we are ambassadors for Christ; it is as though God were appealing through us, and the appeal that we make in Christ’s name is: be reconciled to God. For our sake God made the sinless one into sin, so that in him we might become the goodness of God.
