For the philokalic tradition the burning hearts at Luke 24:32 are a charismatic experience of the divine presence that can best be understood as realised, or inaugurated, eschatology. To make this assertion intelligible, first I introduce philokalic literature as a body of Byzantine writings that map spiritual experiences. Second, I provide a rough inventory of textual occurrences of warm, or burning, hearts in the eighteenth-century Athonite Philokalia. Third, I exemplify this experience as a charism, or sacrament, of the divine presence by adducing hagiographical witnesses, especially the sixth-century Life of St Mary of Egypt. Finally, I interpret the Emmaus narrative as denoting a charismatic experience of the philokalic sort, representative for realised, or inaugurated, eschatology. As critical keys, I draw upon Bucur’s analysis of patristic reception of the Emmaus narrative, Florovsky’s take on eschatology, and Harrison’s views of the Pauline age of grace.
