Obamas take communion at St. John's Episcopal church

The First Family walked from the White House this morning to attend the 9:00 AM choral and Holy Eucharist at St. John's Episcopal Church in Washington, DC, which is also known as "The President's Church." It's located across Lafayette Square Park from the White House, and President Obama held daughter Sasha's hand as the family strolled across the park, accompanied by First Lady Michelle Obama and daughter Malia.
St. John's has a special pew for presidents, nine rows back from the altar, complete with prayer stools that have the names of former presidents embroidered in gold on the red cushions. Attendance was low at the church this morning, with about forty worshipers present. The sermon, from St. John's rector Rev. Dr. Luis Leon, focused on the parable of the dishonest steward from the Gospel of Luke, 16:1-13, which ends "You cannot serve God and wealth." (WEBSITE included photo of Episcopal priest / preacher greeting the Obama family)
Leon said the parable is an instruction to "act shrewdly on behalf of God," and that Luke is advising that listeners make choices about God and "the time to act is now." President Obama invoked the same idea--on a different subject--last night when he spoke at the Phoenix Awards Dinner in Washington, telling black leaders to get the vote out for midterms, because "now is the time for action."
After the sermon, the First Family, led by the President, all went up to the altar rail and took communion. St. John's has an "all access" policy for communion; you do not need to be baptized to go up to the altar, but can receive a blessing by crossing your arms over your chest while kneeling. Today was the First Family's fourth visit to St. John's; they attended just hours before President Obama's inauguration, on Easter Sunday in 2009, and again earlier this year.
The Obamas have never joined a church in Washington; the President has cited an unwillingness to disrupt any congregation by joining. St. John's Episcopal Church's history says that every president since James Madison has attended services at the church.

The First Family walked back home to the White House, following the service.
