X. GLORIOUS KING FLAVIUS RECCESVINTH.
No Jew shall testify against a Christian; and under what circumstances the descendants of Jews may testify.
If he who is convicted of having uttered a falsehood becomes infamous in the sight of all men, with how much more reason should he be excluded from giving testimony who denies the truth of the Divine Faith? Jews, whether baptized or unbaptized, are therefore forbidden to testify against Christians. The descendants of Jews, however, if they are of good morals, and adherents of the Faith, shall be permitted to give evidence among Christians; but not unless their morals and their belief shall be vouched for by either the king, a priest or a judge.
