The logo is an X. In Greek it is chi, the first letter of Christos. In Roman numerals it is ten, for the ten words. The burnt orange of this site recalls the fire on Mount Sinai (Exod. 19:18; 24:17).

The Standards and Scripture

The Westminster Standards.

The Westminster Standards serve as this site's Reformed theological standard and as a guide to Scripture, which stands above them. The Confession affirms that the supreme judge in every dispute of religion is the Holy Spirit speaking in Scripture (1.10), and it confesses that synods and councils may err and are to be used as a help to faith and practice, not as their rule (31.3). The Standards also set out what Scripture teaches about God, the covenants, and the law, whether expressly or by good and necessary consequence (1.6), so that readers can see Eden, Abraham, and Sinai converge on Christ, in whom the covenant of grace is one and the same under its various dispensations (7.6). This site cites the American revision of 1788, as used by the Presbyterian Church in America and the Orthodox Presbyterian Church, which altered the language about the civil magistrate in chapters 20, 23, and 31 of the 1647 Confession.

Work in progress

Future Work.

  • Studies on the commandments. Ten studies, one for each commandment, setting out the duties it requires and the sins it forbids and working through specific cases.
  • AI Governance Tools (forthcoming). Open source tools that help organizations review, approve, and monitor their AI systems against the Decalogue. The ten studies, together with Scripture and the Westminster Standards, will form the reference library the tools draw on through retrieval-augmented generation (RAG), so that every answer cites the passages it rests on.

Contributors who hold to the Westminster Standards are welcome. Write to [email protected] with your proposal, following the contributor standard.
