Can the ancient martyrdom narrative of Perpetua and Felicitas, which is considered by many scholars as a Montanist document, benefit today’s readers? To find an answer to this question I have analyzed the contents and dynamic of the Passion of Perpetua and Felicitas from the perspective of the spiritual practice, using a literary approach. Then, I have compared the Passion with the inner dynamic of the Spiritual Exercises by Ignatius of Loyola, a renowned manual for spiritual practice, in order to prove that the narrative contains the spiritual formation process and spiritual experiences of the martyrs as the witnesses of Christ. Finally, I have examined the value of the martyrdom narrative both for North Korean Christians under persecution and South Korean readers who think that they have nothing to do with martyrdom. Through this process I have contended that the ancient narrative still has precious value for Korean Christians not only because martyrdom still happens in the world, but also because the narrative communicates to today’s readers the spiritual practices of nascent martyrs and their experiences and invites them to live as authentic Christians. In sum, the Passion of Perpetua and Felicitas is a useful resource for today’s Christians to be formed as witnesses of Christ.
