The Integrity of Oaths

The Catechism affirms that swearing an oath is permissible when required for the honor of God and the benefit of one's neighbor.

Is it permissible to swear an oath by the name of God? Yes, if the authority demands it or necessity requires it, in order to uphold loyalty and truth for the honor of God and the well-being of our neighbor. Because such swearing is grounded in God's Word. Therefore, people have rightly made use of it in both the Old and New Testaments.

God Alone as Witness

Swearing by creatures or saints is forbidden because an oath is a solemn appeal to God, the only one who knows the heart.

Can one also swear by the saints or other creatures? No; because in a lawful oath, I call upon God Himself as a witness that He, who alone knows the hearts, will confirm the truth and punish me if I swear falsely. But this honor belongs to no creature.

Read the original Latin

Darf man aber überhaupt bei dem Namen Gottes einen Eid schwören? Ja, wenn es die Obrigkeit fordert oder die Not es gebietet, auf diese Weise Treue und Wahrheit zu Gottes Ehre und des Nächsten Wohl zu erhalten und zu fördern. Denn solches Schwören ist in Gottes Wort begründet. Deshalb haben die Menschen im Alten und Neuen Testament zu Recht davon Gebrauch gemacht.

Darf man auch bei den Heiligen oder anderen Geschöpfen schwören? Nein; denn in einem rechtmäßigen Eid rufe ich Gott selbst zum Zeugen an, dass er, der allein die Herzen kennt, die Wahrheit bestätige und mich strafe, wenn ich falsch schwöre. Diese Ehre aber gebührt keinem Geschöpf.
