Keyser, Leonhard, a Baptist martyr, originally a Roman Catholic priest, flourished in the first half of the 16th century. Ile joined the Baptists in 1525, and immediately began preaching the Reformation doctrine, undismayed by all the tyranny exerted against the faithful by water, fire, and sword. In the second year of his ministry (1527) he was apprehended at Scherding, on the River Inn, and condemned to the flames. "The chief heads of accusation against him were, that faith alone justifies, without good works; that there are only two sacraments; that the Gospel was not preached by the papists in Germany; that confession is not God's command; that Christ is the only satisfaction for sin; that there is no purgatory; that Christ is the only Mediator; and that all days (alluding to feast or saints' days) are alike with God."-Baptist Martyrs, p. 60.
