The mass began with a Polish military song and a parade of local scouts and clergy. The President and his wife received a round of applause when they entered the church.
The ceremony commenced in mostly Polish.
One member of the clergy read a passage from Luke 16:13 in English: “No one can serve two masters. Either you will hate the one and love the other, or you will be devoted to the one and despise the other. You cannot serve both God and money.”
President Duda sat in the front row next to his wife, singing and praying along with a packed house of parishioners.
The mass ended with both the Polish national anthem and “God Bless America.”
As they exited the church, the Polish delegation received a standing ovation as the First Lady waved to the crowd.
