Mercy has understood to be a given-to-human divine gift. Human beings, on their behalf, should correspond to it by being merciful to others. This understanding nonetheless entails certain pitfalls, which leads to rethinking mercy otherwise. Thus, this work proposes a renewed way to comprehend mercy, through a phenomenological reading of Origen’s Communio Sanctorum, as an anthropological experience. An analytical description of the phenomenon will be developed to elicit the structures included therein. Afterward, loving enemies will be the cornerstone to determine whether living mercy in a radical fashion could be possible humanly. Crucified Jesus will show the path to acknowledge mercy as a trinitarian metamorphosis, including experiences between human beings in via and the departed in God.
