In an interview with the Guardian, Bishop Michael Curry said many leaders of Christianity are "buying into political agendas that very often do not reflect the teaching of Jesus of Nazareth".
"We as Christian leaders must speak up and bear witness to the values that we hold based on the teachings of Jesus. And when we fail to do so, we've failed to represent the Christian faith in the public sphere".
Bishop Michael is the current presiding bishop and primate of The Episcopal Church, a member of the global Anglican Communion.
The Bishop, whose sermon at the royal wedding received mixed reviews from Christians, received a global platform he did not have before, which he is now using to expand more on his sermon and book, The Power of Love.
He said that Christians who claim to follow Jesus but do not obey the commands to love and serve the poor should assess their faith.
He said: "I'm concerned when I don't hear other religious leaders standing up for immigrants in our country being treated with justice and decency. I'm concerned when I don't hear Christian leaders advocating vociferously for the re-unification of parents and children at our borders.
"I'm concerned when I don't hear religious leaders advocating for children to be number one on the social agenda of this country. I'm concerned when I hear silence from religious leaders after the Ku Klux Klan and neo-Nazis marched through the streets of Charlottesville. I'm not hearing Jesus of Nazareth when I hear that silence.
"We as Christian leaders must speak up and bear witness to the values that we hold based on the teachings of Jesus. And when we fail to do so, we've failed to represent the Christian faith in the public sphere."
