F5 · Virgin birth and incarnation
Conceived by the Holy Spirit, born of the Virgin Mary.
Tier: First-order (scoring weight 3). How the tiers were set: theological triage. Method: conventions. Traditions’ sources: confessional sources.
In short
Matthew and Luke both say Jesus was conceived by the Holy Spirit without a human father and born of the virgin Mary. The Word himself became flesh without ceasing to be God — not a mere man later adopted. The earliest fathers confess this, and all nine traditions hold it.
Plan
Question: F05.1: was Christ conceived by the Holy Spirit and born of the Virgin Mary? Scripture: Isa 7:14; Matt 1:18–25; Luke 1:26–38; Gal 4:4. Fathers: Ignatius, Ephesians 18–19 and Smyrnaeans 1; Justin, 1 Apology 33. F05.2: did Christ take flesh from Mary (Gal 4:4; Rom 1:3; Irenaeus III.22.1)? F05.3: did the incarnation unite the Word to human nature without his ceasing to be God (John 1:14; Phil 2:6–8; Ignatius Ephesians 7; Irenaeus III.19; Athanasius On the Incarnation 8, 17)?

Overall verdict
All nine confess the virginal conception, as do Scripture and the fathers from Era I. All nine confess that the Word himself became man without ceasing to be God (F05.3). (Mary’s perpetual virginity is a separate, second-order question under S18.) On F05.2 the Mennonite celestial flesh departs from Scripture and Irenaeus.
Verification status
None beyond standard creedal wording.
