Churches can remain open for private prayer during the two-week circuit breaker, Arlene Foster has confirmed.
The First Minister made the announcement after Stormont ministers met yesterday.
Church leaders across Northern Ireland had asked for urgent clarity about tougher restrictions due to come into force on Friday.
The executive had initially agreed that places of worship should close for all but weddings, civil partnerships and funerals until December 11.
Churches will also be allowed to carry out drive-in services.
Mrs Foster said: "This weekend sees the beginning of Advent and we have agreed that it is important that all places of worship can remain open for individual prayer.
"The Executive also confirmed that drive-in services are permitted.
"It is hoped that these small adjustments will help to maintain wellbeing and reduce pressure as we ask everyone to really dig deep and support the two week effort to bring down rates of infection."
Ministers also agreed that a controlled "click and collect" retail service can operate during the circuit breaker.
It will be permitted to operate on an appointment-only basis from November 27.
Urgent engagement will take place with shopkeepers on strict arrangements under which such a service may continue.
Eligible businesses will still be able to access financial support schemes during this period.
Retail NI chief executive Glyn Roberts said he was pleased ministers had responded positively to the industry's calls.
"This is good news for many struggling retailers who face a difficult two-week circuit breaker and for consumers who are able to continue their Christmas shopping with more choice."
"Increasing numbers of independent retailers are now offering a click and collect service and we urge shoppers to make a special effort to support them in these challenging few weeks."
Ministers also confirmed that outdoor visitor attractions will be closed for the duration of the two weeks; and that self-catering accommodation will only be permitted to operate on a restricted basis, in line with arrangements in place for other accommodation providers, including hotels.
Deputy First Minister Michelle O'Neill said: "The Executive took a difficult but necessary decision last week to introduce two weeks of restrictions, from this Friday, to reduce the spread of coronavirus, save lives, and protect the health service and its workers from unimaginable pressure.
"We understand the implications of these restrictions, and have moved to urgently put in place a further £300 million support package for those affected.
"We have listened to views on a range of issues and agreed that retail businesses will be able to operate a click and collect service in a controlled manner that helps to ensure the safety of both customers and staff."
