The church decided that the service could be safely ended after a grand compromise between the four parties of the Netherlands’ governing coalition. The parties provisionally agreed on Tuesday that up to 700 families who had been previously listed for deportation, despite having lived in the Netherlands for more than a decade in some cases, could have their cases reassessed.

The announcement constituted a radical policy reversal for some of the parties. One government minister had previously described the Tamrazyan family’s fate as “hopeless.”

“For me, I hope it shows that wherever you are in the world, you can raise your voice,” said Tim Hofman, a filmmaker whose documentary about families like the Tamrazyans was instrumental in raising awareness about their fate. Mr. Hofman also started the petition against their deportation.

Though no instructions have yet been issued to the Dutch Civil Service, and no family’s fate has been confirmed, Mr. Stegeman said he had been assured by several political leaders on Tuesday night that the status of the Tamrazyan family would be among those reassessed.

That encouraged Mr. Stegeman and his colleagues to halt the service, which began last fall in secret and with few congregants present but ended on Wednesday afternoon with an emotional final communion in front of a packed chapel.

“It was very emotional, very humorous. We laughed a lot, we applauded for a long time,” Mr. Stegeman said.
