The call, made by the Catholic Parliamentary Office, came in response to the Scottish Government’s review into current hate crime legislation.
In its response, the Church highlighted the history of anti-Catholicism in Scotland.
Director of the Catholic Parliamentary Office, Anthony Horan, said: “Having devoted significant resources to the symptoms of sectarianism, it is now appropriate that some attention is being given to its cause, through this review.
The Scottish Government’s public consultation into the hate crime review closed last week.
Lord Bracadale, who is undertaking the review, said: “We are now analysing the responses received, and will take these into account as I prepare my recommendations on hate crime legislation in Scotland.”
