In a Statement released today (full text), President Biden and Jill Biden sent greetings to Orthodox Christians who are celebrating Christmas today. The Statement says in part:
Today, we pray for Orthodox Christians who are suffering around the world due to war, conflict, deprivation, and oppression. They, like all human beings, are created in the image of God, and deserve safety and security, dignity and respect. We will continue to advocate for these core principles, including religious freedom, and on this day, we keep these communities close to our hearts.
