Adrian Schonfelder is running for Labor in the safe Liberal-held Victorian seat of Flinders.
He has told a local newspaper that Mr Abbott's conservative religious views are "influencing people to take their own lives".
He singled out the Opposition Leader's religious views on sex before marriage and abortion.
Mr Schonfelder has since been forced to issue a retraction, saying he regrets any offence caused by the remarks.
Bit of a worry really...
