Earlier this week I found the Reconquista movement, with its Episcopal version, which details a plan to "re-conquer" historic denominations and take over their property, resources, and reputation with a form of exclusionary Christian faith. In these pages, we find "95 Theses" which are a syncretistic mixture of three strands of incompatible ideas:
First, there are ancient Creedal beliefs about the Triune God, incarnate in the Lord Jesus Christ, who works through the Holy Spirit to extend the mission and incarnation of Christ through the sacramental community of the Church.
Second, there are explicitly Reformed or Calvinist or "Evangelical" framings of the Nature of God and of salvation which are historically rejected by most non-Reformed Christians (such as Catholics, Orthodox, and non-Reformed Protestants).
Third, there are modernist exclusionary stances to reject certain social/racial critiques, political-economic ideas, and gender/sexual identities, while at the same time implicitly or explicitly affirming other modern categories of race, social structure, politics, economics, gender, and sexuality.
This is to say they do precisely what they accuse others of doing: They use reformed and modern categories to view and mold the Ancient Creedal Faith, rather than interpreting theology and culture through the lens of the Ancient Creeds.
