Whether joy is effected in us by charity?

Objections

Objection 1 : It would seem that joy is not effected in us by charity. For the absence of what we love causes sorrow rather than joy. But God, Whom we love by charity, is absent from us, so long as we are in this state of life, since "while we are in the body, we are absent from the Lord" (2 Cor. 5:6). Therefore charity causes sorrow in us rather than joy.
Objection 2 : Further, it is chiefly through charity that we merit happiness. Now mourning, which pertains to sorrow, is reckoned among those things whereby we merit happiness, according to Mt. 5:5: "Blessed are they that mourn, for they shall be comforted." Therefore sorrow, rather than joy, is an effect of charity.
Objection 3 : Further, charity is a virtue distinct from hope, as shown above (Question [17], Article [6]). Now joy is the effect of hope, according to Rm. 12:12: "Rejoicing in hope." Therefore it is not the effect of charity.
