St Mary's in Horsham turned its chapel to a 'Brexit stress chapel'.
Curate Rebecca Tuck told Premier some members of the church came up with the idea.
"A couple of members of our church thought that leading up to October 31, that we'd really like to do something to help people pray at this difficult time.
"People still have anxiety and many people in our town and in our church are concerned about the outcomes and what's going to happen, so they wanted to support people in being able to pray about this situation."
The Brexit stress chapel opened on Sunday after the church's 9:30am service.
In it are interactive prayer stations which encourage people to pray over certain issues relating to Brexit.
"We've also got a map of our nation and some plasters," Tuck explained.
"So you can take a plaster and you can write on it areas where you'd like to see healing take place.
"People have written words like humility, peace, calm and lower stress and they've stuck them on the map to pray for different areas of our country,"
Horsham MP Jeremy Quin, who's a member of St Mary's, will also give regular updates about what to pray about regarding Brexit negotiations continue.
Tuck said the chapel, which is also open for the public to use, has been well-received.
She said the main aim of it is to remember the importance of prayer.
"We're not trying to make a political statement," she told Premier.
"It's open to everybody, whatever their views. It's an invitation to pray because prayer is a positive action that we can take this time of uncertainty.
"People might feel worried or anxious about what's going to happen but one thing that we know we can do is pray.
"We might not have control over the situation but we know that that when we pray, God is at work."
