Haiti
Lord have mercy. Horrific is the only word to describe conditions in Haiti after their massive earthquake.
Fr. Jonathan Tobias has good thoughts in "What Orthodox Christians do about the Earthquake in Port au Prince," here. His advice? Pray for mercy, repeatedly, profligately. Give. Repeatedly. Profligately. Do not try to figure out how your gifts will make a difference. Now is not a good time to be an accountant.
One easy way to contribute is texting 90999 on your phone, then typing in the word, Haiti. This will automatically donate $10 to the Red Cross effort there.
The International Orthodox Christian Charities site is here.
Mercy Ships, an organization based in my area, has a long track record of providing real emergency assistance and humanitarian aid. Their site, here.
