The Orange Order has asked its members to stop using the term 'RIP' to express grief or sympathy after a death.
It said the phrase is unbiblical, un-Protestant, and a form of superstition connected to Catholicism.
RIP is an abbreviation of 'rest in peace' or in Latin, 'requiescat in pace'.
In a publication marking the 500th anniversary of the Reformation, the order called on Protestants to stop using the phrase.
Wallace Thompson, secretary of Evangelical Protestants Northern Ireland, wrote a Facebook post on which the article was based.
He told the BBC's Talkback programme: "Observing social media, we have noticed that the letters RIP are used a lot by Protestants, and by some evangelical Protestants."
Mr Thompson explained that for him, 'RIP' is a prayer and he did not encourage prayers for the dead.
"From a Protestant point of view, we believe, when death comes, a person either goes to be with Christ for all eternity, or into hell.
yes. It's complete BS. the bible says we remain in the grave until God's trumpet call Daniel 12:2 raised to glory or condemnation. at that point your soul ascends to Christ. You slept, you know nothing and time did not move for you. so being dead 500 years or a year, is the same. there is no rest for the wicked. judgment will come to those that don't accept the free pardon. As a very lazy man a rest would be appreciated. I'm not sure about continuing for eternity - sounds like a dreadful job. protestants will love the idea of working away for eternity? very Calvinist.
