In light of women’s marginal status in church governance and ministry through most of recorded history, feminist trinitarian ecclesiology is needed to transform the church’s institutional and spiritual life. While Vatican II provided the paradigm shift and promising anthropology essential for an egalitarian church, feminist ecclesiology prompts a radical transformation of its hierarchical and patriarchal structures and practices so that it may truly embody the Trinity. Trinitarian life provides practical and radical consequences for Christian life, and provides a model of church marked by relationships of equality, mutuality, unity and reciprocity. It also provides a strong ecclesiological argument for reform of the juridical Catholic nullity of marriage process, which may pave a pathway for the civilly remarried to receive the sacraments of Reconciliation and Holy Eucharist.
