The Emperor Constantine revolutionised the Empire by giving a chief place to Christian doctrines and practices. He issued an edict of toleration in 313; decreed the observance of Sunday, the use of prayer in the army; abolished the punishment of crucifixion, gladiatorial games, infanticide, private divinations; and encouraged slave emancipation. He was a great admirer of good preaching. Eusebius says he himself once delivered a sermon in the palace before the marvellous man on the Church of the Holy Sepulchre. There was a crowded audience. The Emperor stood erect the whole time; would not be induced to sit down on the throne close by; paid the utmost attention; would not hear of the sermon being too long; insisted on its continuance; and on being entreated to sit down, replied, with a frown, that he could not bear to hear the truths of religion in any easier posture. More often he was himself the preacher, and one sermon of his is preserved by Eusebius. These sermons were always in Latin, but they were translated into Greek by interpreters appointed for the purpose. On these occasions a general invitation was issued, and thousands of people flocked to the palace to hear the Emperor do duty as the preacher. He stood erect, and then with a set countenance and grave voice poured forth his address, to which, at the striking passages, the audience responded with loud cheers of approbation. He usually discoursed on the follies of Paganism, the scheme of Providence and redemption, and the avarice and rapacity of courtiers. THE LAST ILLNESS OF CONSTANTINE (A.D. 337).
