The word martyr, from the Greek, means witness; but those who
testified for Truth were so often persecuted unto death, that at length
the word martyr was narrowed in its significance and so has come
always to mean one who suffers for his convictions.
The new faith in the Christ, Truth, so roused the hatred of the
opponents of Christianity, that the followers of Christ were burned,
crucified, and otherwise persecuted; and so it came about that human
rights were hallowed by the gallows and the cross.
