Beloved, if God so loved us, we ought also to love one another.

Dearly beloved, if God so loved us, &c. If here is not a particle expressive of doubtfulness. It is not conditional, but causal, and is equivalent to because. It means, Because God so loves us. Christ uses a similar construction, when He says, "If I, your Lord and Master, have washed your feet, ye also ought to wash one another"s feet."
S. John says if, rather than because, for the sake of greater weight and pathos, as it were lost in amazement at the infinite love of God. Wherefore it is advisedly and intentionally that he says after the antecedent, if God so loved us, not we therefore ought so to love God, which is impossible, but, we ought also to love one another. As much as to say, Since we cannot render equal love in return for Divine love, let us at least love one another according to our slender capacity. For what we do to our neighbour God accounts as done to Him.
The word us includes also our neighbours. If God, who is not a partaker, vouchsafes to love all who participate in our nature, how much more does it become us to embrace with our love all who are of the same nature, and in respect of it are equals? Truly does S. Augustine say on this passage (Tract7): "Love, and do what thou wilt. For if thou art silent, thou keepest silence through love. If thou criest out, thou criest out in love. If thou correctest, thou correctest lovingly. If thou sparest, thou sparest in love. Let this be the root of love within. From that root nothing but love can spring."
