10-Point Theological Scorecard
Christology
Is Jesus the only way? (John 14:6)
Heidelberg Catechism (Q&A 29–52) and Belgic Confession (Articles 18–21) confess orthodox Trinitarian and Chalcedonian Christology.
Strong
Scripture
Inerrancy affirmed? Final authority?
Belgic Confession Articles 3–7 affirm the inspiration, sufficiency, and authority of canonical Scripture as the rule of faith.
Strong
Men's Discipleship
Intentional formation for men?
Family worship, catechism instruction, and male headship in home and church are emphasized in the German Reformed tradition.
Strong
Soteriology
Faith alone? How is salvation presented?
Three Forms of Unity — monergistic regeneration, sola fide, sola gratia, sola Scriptura, particular redemption per the Canons of Dort.
Strong
Gender / Biblical Design
Biblical manhood and womanhood by God's design — patriarchal, complementarian, egalitarian, or affirming gender ideology?
RCUS Constitution restricts the offices of minister, elder, and deacon to qualified men only — male-only ordained officers.
Strong
Leadership Structure
Male elders/pastors? Accountability?
Plurality of male elders (consistory) under presbyterial-classical polity (classis and synod).
Strong
Preaching Style
Expository or topical/therapeutic?
Catechetical preaching (Heidelberg Catechism Lord's Day series) is standard RCUS practice in the second service or Sunday school.
Strong
Mission Clarity
Great Commission central?
RCUS supports Westminster Biblical Missions and partners with NAPARC churches in domestic and foreign missions.
Strong
Cultural Alignment
DEI/CRT language? Social justice crowding out gospel?
RCUS / Eureka Classis fought a successful theological and legal battle to continue as the true RCUS when the parent body merged into the Evangelical and Reformed Church in 1934 — paradigmatic confessional resistance.
Strong
Accountability Structure
Denominational home, elder plurality, or external network — is the pastor answerable to anyone?
Reformed Church in the United States — German Reformed heritage tracing to Boehm's 1725 organization in Pennsylvania; the modern RCUS preserves the Eureka Classis line.
Strong
