The Bishop of Sheffield has been targeted for speaking out against the far right party, the BNP.
The Rt Reverend Jack Nicholls revealed at a public rally that he received abuse from BNP supporters for urging voters to reject the BNP.
The news followed action by the heads of major churches across West Yorkshire, who gathered this week in Leeds to sign a ìhistoric joint statement deploring the racist policies of the BNP and calling on Christian people to use their voteî.
Speaking at the Sheffield Unite Against Fascism conference Bishop Jack said: "I have received some of the most vitriolic correspondence as a result of speaking out...that I have ever had.
"You would not believe - and it is not too strong a word to use - the evil that is brought to the surface by issues such as this."
Most of the abuse had been sent by e-mail or post.
He said: "The language they used was simply filthy, accusing me of interfering in things that did not concern me and telling me I should understand that these immigrants are scum."
Other denominations have also been speaking out against the BNP. The Methodist Church last week launched an initiative called"Countering Political Extremism" which is an online information resource for churches concerned about the rise of far-right political parties such as the BNP.
A teacher at a catholic school was also this week suspended for standing as a BNP candidate in the forthcoming elections.
The BNP has said it intends to stand a record number of candidates in Yorkshire.
It is feared the BNP may need less than 10 per cent of the electorate to support them to return a MEP if turnout in the local elections is poor.
