But, after all, the force of the Christian movement lay neither in church, nor in sacrament, but in men. "How did Christianity rise and spread among men?" asks Carlyle, "was it by institutions, and establishments, and well arranged systems of mechanism? No! ... It arose in the mystic deeps of man's soul; and was spread by the 'preaching of the word,' by simple, altogether natural and individual efforts; and flew, like hallowed fire, from heart to heart, till all were purified and illuminated by it. Here was no Mechanism; man's highest attainment was accomplished Dynamically, not Mechanically."[51] Nothing could be more just. The Gospel set fire to men's hearts, and they needed to do nothing but live to spread their faith. The ancient evidence is abundant for this. The Christian had an "insatiable passion for doing good"[52]--not as yet a technical term--and he "did good" in the simplest kind of ways. "Even those things which you do after the flesh are spiritual," says Ignatius himself, "for you do all things in Jesus Christ."[53] "Christians," says a writer whose name is lost, "are not distinguishable from the rest of mankind in land or speech or customs. They inhabit no special cities of their own, nor do they use any different form of speech, nor do they cultivate any out-of-the-way life.... But while they live in Greek and barbarian cities as their lot may be {160} cast, and follow local customs in dress and food and life generally, ... yet they live in their own countries as sojourners only; they take part in everything as citizens and submit to everything as strangers. Every strange land is native to them, and every native land is strange. They marry and have children like everyone else--but they do not expose their children. They have meals in common, but not wives. They are in the flesh, but they do not live after the flesh. They continue on earth, but their citizenship is in heaven. They obey the laws ordained, and by their private lives they overcome the laws.... In a word, what the soul is in the body, that is what Christians are in the world."[54]
