Theorem bj-vtoclg1f 32103

Description: Reprove vtoclg1f 3238 from bj-vtoclg1f1 32102. This removes dependency on ax-ext 2590, df-cleq 2603 and df-v 3175. Use bj-vtoclg1fv 32104 instead when sufficient (in particular when 𝑉 is substituted for V). (Contributed by BJ, 14-Sep-2019.) (Proof modification is discouraged.)

Hypotheses

Ref	Expression
bj-vtoclg1f.nf	⊢ Ⅎ𝑥𝜓
bj-vtoclg1f.maj	⊢ (𝑥 = 𝐴 → (𝜑 → 𝜓))
bj-vtoclg1f.min	⊢ 𝜑

Assertion

Ref	Expression
bj-vtoclg1f	⊢ (𝐴 ∈ 𝑉 → 𝜓)

Distinct variable group:   𝑥,𝐴

Allowed substitution hints:   𝜑(𝑥)   𝜓(𝑥)   𝑉(𝑥)
