With the subsistit formula, Vatican II intended - in line with the Catholic tradition - to say something the exact opposite of “ecclesiological relativism”: there is a Church of Jesus Christ. He himself willed her existence, and ever since Pentecost the Holy Spirit is constantly creating her, despite all human failures, and preserves her in her substantial identity. The institution is not an unavoidable - although theologically irrelevant or even damaging - external phenomenon; it is, in its essential core, a part of the concrete character of the Incarnation. The Lord is keeping his word: “The gates of hell shall not prevail against it.” Pilgrim Fellowship of Faith, “The Ecclesiology of the Constitution Lumen Gentium”, Ignatius Press.
