Christian Gratitude
May we then swear religiously by the name of God?
Yes: either when the magistrates demand it of the subjects; or when necessity requires us thereby to confirm a fidelity and truth to the glory of God, and the safety of our neighbour: for such an oath is founded on God’s word, 1 and therefore was justly used by the saints, both in the Old and New Testament. 2
May we also swear by saints or any other creatures?
No; for a lawful oath is calling upon God, as the only one who knows the heart, that he will bear witness to the truth, and punish me if I swear falsely; 3 which honour is due to no creature. 4
