A.T. Robertson Commentary Titus 3:4

"But when the kindness of God our Saviour, and his love toward man, appeared," — Titus 3:4 (ASV)

The kindness (η χρηστοτης). See Ro 2:4 for this very word used of God as here.

His love toward man (η φιλανθρωπια). "The philanthrophy of God our Saviour." Old word from φιλανθρωπος, for love of mankind, in N.T. only here and Ac 28:2.

Appeared (επεφανη). See 2:11 and here as there the Incarnation of Christ. See 1 Timothy 1:1 for σωτηρ with θεος (God).
