The leaders of 16 places of worship received a certificate of recognition during a ceremony hosted at the city hall by Lord Mayor of Bradford, Councillor Zafar Ali, on Tuesday afternoon.
Rev Chris Chorlton, rector of St Paul's Church in Manningham - one of the churches involved - said the scheme is just one way different local faith groups co-operate.
He told Premier: "Churches and mosques have been working together for a long time; people of faith in this city acknowledge it's important to work together.
"The scheme is more a greet-and-greet, and a time to acknowledge the work that has been going on."
We were delighted to host faith leaders from 16 different places of worship, from all across the district today, as part of a special 'twinning' project to bring together people of different faiths and backgrounds #TeamBradford pic.twitter.com/WdUAfyrVSj

At least two religious communities in six of Bradford's local districts have committed to meet twice-per-year and work together on a joint project.
In signing up to the "twinning project" - the first scheme of its kind in the UK - they also agree to honour each other's beliefs and offer support during moments of crisis.
Rev Chorlton continued: "We've done litter picks; we do faith trails [walks along a route connecting different places of worship].
"I'll go to an assembly if it's Eid and then a Muslim representative will go to my assembly if I'm speaking about Christmas or Easter. So, we have a lot of ways in which we connect together.
