A Christian is one

who recognizes Jesus as the Christ, the Son of the living God, as God manifested in the flesh, loving us and dying for our redemption;

and who is so affected by a sense of the love of this incarnate God as to be constrained to make the will of Christ the rule of his obedience, and the glory of Christ the great end for which he lives.

—Charles Hodge, An Exposition of the Second Epistle to the Corinthians (1863), p. 133.
