Thousands gathered at Christ Tabernacle Church in Queens, N.Y., to say a final farewell to Rafael Ramos, one of two officers who was gunned down in an ambush last week.

Vice President Joe Biden, New York Gov. Andrew Cuomo and New York Mayor Bill de Blasio were among the attendees of the funeral service, which was held at the church Ramos attended for 14 years.

Biden addressed the slain officer’s two sons, telling them that the NYPD will always have their backs.

“Know that although your father is gone, you have inherited an entire family. The men and women of the New York Police Department will always be there as long as you are alive. They never, they never, never forget,” Biden said.

New York Police Commissioner Bill Bratton made Ramos an honorary department chaplain of the 84th Precinct. Ramos had been studying to become a pastor.

Ramos and his partner, Officer Wenjian Liu, were also posthumously promoted to first-grade detective.

Cuomo reaffirmed that the city stands with the NYPD, calling it the greatest police department in the world.

“The NYPD protected the right of freedom of speech even though they themselves were the target of false and abusive chants and tirades by some. What a beautiful testament to their professionalism,” he said.

Thousands of officers lined the streets as some of New York's finest carried Ramos' casket from the church.

Funeral plans for Liu have not yet been announced.
