But respecting Felicitas (for to her also the Lord's favour approached in the same way), when she had already gone eight months with child (for she had been pregnant when she was apprehended), as the day of the exhibition was drawing near, she was in great grief lest on account of her pregnancy she should be delayed,—because pregnant women are not allowed to be publicly punished,—and lest she should shed her sacred and guiltless blood among some who had been wicked subsequently. Also, her fellow-martyrs were painfully saddened lest they should leave so excellent a friend and companion, alone in the path of the same hope. Therefore, joining together their united cry, they poured forth their prayer to the Lord three days before the exhibition. Immediately after their prayer her pains came upon her, and when, with the difficulty natural to an eight months' delivery, in the labour of bringing forth she was sorrowing, some one of the servants of the prison guards said to her, "You who are in such suffering now, what will you do when you are thrown to the beasts, which you despised when you refused to sacrifice?" And she replied, "Now it is I that suffer what I suffer; but then there will be another in me, who will suffer for me, because I also am about to suffer for Him."
