You can become a member of Mere Orthodoxy. Members receive our print edition as well as gaining access to member-only email content and access to the Mere Orthodoxy Members Discord server.
You can give a tax-deductible gift to Mere Orthodoxy through our portal on the New Horizons Foundations website.
Third, we have had a Patreon so if you wish to give a recurring donation and are not worried about your gift being tax-exempt, you can give there.
