Giving to the collection basket at mass might count as a corporal act of mercy, as any almsgiving may contribute to the execution of such an act:
The money might be used by the parish to supplement their food bank to feed the hungry;
it might also be used for programs buying fresh water for third world countries, and thus to give drink to the thirsty;
or to buy a warm winter coat or pair of shoes for the homeless, it might be an example of a means to clothe the naked;
It could be used to finance a homeless shelter or safehouse for abused spouses and children, so it could be to harbour the harbourless;
The money might be used to pay for gas for priests and ministers to make trips to hospitals, hospices, nursing homes, to visit the sick;
It could be used to fund drug and alcohol treatment and counseling programs to free those enslaved by addition, a means to ransom the captive;
or even to pay funeral expenses for the indigent, or unknown dead (including unborn children victims of abortion), which would be to bury the dead.
Be a joyful giver!
Peace and all good!
