An Anglican church on the Gold Coast has posted an unintentionally lewd message on its roadsign sign, raising some eyebrows from passers-by.

"Forgiveness is swallowing when you would rather spit," the sign reads outside the Surfers Paradise Anglican Church of the Holy Spirit, on Salerno Street at the Isle of Capri.

Surfers Paradise MP John-Paul Langbroek shared a photo of the sign on Twitter, saying it was 'church signs done differently'.

A spokeswoman for the church said the senior minister, Mike Uptin, put the sign up yesterday but he was not available to speak to the media as it was his day off.
