The emptiness and corruption of paganism was the negative, the divine power of the gospel was the positive, means of this wonderful extension. This divine power was manifested in the zeal and self-denial of Christian teachers and missionaries (§ 34, 1), in the life and walk of Christians, in the brotherly love which they showed, in the steadfastness and confidence of their faith, and above all in the joyfulness with which they met the cruellest of deaths by martyrdom. The blood of the martyrs was the seed of the church, and it was not an unheard-of circumstance that the executioners of those Christian witnesses became their successors in the noble army of confessors. § 22. PERSECUTIONS OF THE CHRISTIANS IN THE ROMAN EMPIRE.[22] The Law of the Twelve Tables had already forbidden the exercise of foreign modes of worship within the Roman empire (_Religiones peregrinæ_, _Collegia illicita_), for religion was exclusively an affair of the state and entered most intimately into all civil and municipal relations, and on this account whatever endangered the national religion was regarded as necessarily imperilling the state itself. Political considerations, however, led to the granting to conquered nations the free use of their own forms of worship. This concession did not materially help Christianity after it had ceased, in the time of Nero, to be regularly confounded by the Roman authorities with Judaism, as had been the case in the time of Claudius, and Judaism, after the destruction of Jerusalem, had been sharply distinguished from it. It publicly proclaimed its intention to completely dislodge all other religions, and the rapidity with which it spread showed how energetically its intentions were carried out. The close fellowship and brotherliness that prevailed among Christians, as well as their exclusive, and during times of persecution even secret assemblies, aroused the suspicion that they had political tendencies. Their withdrawal from civil and military services on account of the pagan ceremonies connected with them, especially their refusal to burn incense before the statues of the emperor, also the steadfastness of their faith, which was proof against all violence and persuasion alike, their retiredness from the world, etc., were regarded as evidence of their indifference or hostility to the general well-being of the state, as invincible stiff-neckedness, as contumacy, sedition, and high treason. The heathen populace saw in the Christians the sacrilegious enemies and despisers of their gods; and the Christian religion, which was without temples, altars and sacrifices, seemed to them pure Atheism. The most horrible calumnies, that in their assemblies (_Agapæ_) the vilest immoralities were practised (_Concubitus Œdipodei_), children slain and human flesh eaten (_Epulæ Thyesteæ_, comp. § 36, 5), were readily believed. All public misfortunes were thus attributed to the wrath
