A dear friend sent me this article. What does it have to do with reuniting all Christians? This I think:
"And I, if I am lifted up from the earth, will draw all men to Myself." (John 12:32)
"For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places." (Ephesians 6:12)
For more on the Sisters of Ephesus, see their web site and their blog. In the times of darkness, the monastery and the convent have been the unconquerable sources of light and hope and transforming power.
"Let unity, the greatest good of all goods, be your preoccupation." - St. Ignatius of Antioch (Letter to St. Polycarp)
