In the past it meant going out to the find the poor or letting them into our comfort zone, it meant being disturbed by them, seeing, smelling their poverty for ourselves and even risking our safety in our encounter with them.
Giving alms to the sick could well risk catching their sickness or coming home with fleas or worse. Almsgiving is about solidarity with the poor but also education of the rich.
Remember Chrysostom: If we give from our excess we are doing nothing but returning what we have grabbed for ourselves, almsgiving is about giving from your necessities.
The late Father John Edwards SJ used to say: you can tell where your heart is and what is important to you by looking at yout bank statement.
