Religious instruction classes will be reintroduced into the Victorian state school curriculum if the Coalition wins next month's election.

Opposition leader Matthew Guy made the announcement at an Australian Christian Lobby pre-election forum on the weekend which also discussed euthanasia, gender theory, safe schools and religious freedoms.

"A government I lead will bring back religious instruction in schools because it's very important," Mr Guy told the crowd at Crossway Baptist Church in Burwood East.

He also reiterated his party's promise to abolish the contentious Safe Schools program and said he was not ashamed to say he was a Christian.
