    Apophasis, Abnegation, and Liturgy by David W. Fagerberg

    Published 2022-12-01
    “…However, such a liturgical posture depends, in turn, upon abnegation. The infinity of God (apophasis) reveals our nothingness (abnegation), and our nothingness makes us rejoice (liturgy) in God’s infinity. …”
