The leader of the group Christians in Politics is urging believers to reflect on the words they use in light of recent political controversies.
Boris Johnson is being called by his own party to apologise after he wrongly suggested Sir Keir Starmer had failed to prosecute Jimmy Saville in a previous job.
The Labour leader was mobbed by protesters in Westminster yesterday.
Andy Flanagan, Executive Director from Christians in Politics spoke to Premier said: “One of the things we have been saying for a long time at Christians for Politics is the importance of our words and that it is important to have integrity in politics.
“Words matter, as we know words can bless and curse and we can speak good things and bad things into being, they are profound.
“When words aren’t true and emerge into the atmosphere it can give credence and they can give energy and they can give volume.”
“There is space needed for reflection and perhaps the Prime Minister would be able to take that time to reflect because actually it is really difficult being in the public eye, in the eye of the storm.
“I think it’s something that we should be praying for, that they do have time to reflect.”
In a tweet Boris Johnson said the behaviour directed at Sir Keir on Monday afternoon was "absolutely disgraceful" and "completely unacceptable."
Downing Street said that Boris Johnson has no intention of apologising about his comments he made.
