Former Air NZ chief turned National MP Christopher Luxon defended his Christian faith in his maiden speech in Parliament.

Speaking last night, Luxon – who was elected to Parliament for the first time last year as the MP for Botany – told Parliament: "It seems it has become acceptable to stereotype those who have a Christian faith in public life as being 'extreme', so I will say a little about my Christian faith.

"It has anchored me, given my life purpose and shaped my values – and it puts me in the context of something bigger than myself," he said.

His faith had a strong influence on who he was and how he related to people.

"I see Jesus showing compassion, tolerance and care for others. He doesn't judge, discriminate or reject people. He loves unconditionally."

Throughout history, Christians had made a huge difference in public life.

"Christian abolitionists fought against slavery. Others educated the poor and challenged the rich to share their wealth and help others less fortunate."

The world was a better place for Christians such as William Wilberforce, Martin Luther King and Kate Sheppard contributing to public life.

"My faith is personal to me," said Luxon.

"It is not in itself a political agenda. I believe no religion should dictate to the state. And no politician should use the political platform they have to force their beliefs on others.
