Donald Trump continues on the road to become one of the most polarising figures among Christians in a generation as one church in Auckland demonstrated their opposition to his "unChristian" even as he continues to be the leading candidate among US evangelicals in exit polls.

According to a report by The Blaze, The Community of Saint Luke in Auckland, New Zealand recently posted a cartoon on their social media page depicting Trump nailing Jesus to a cross.

The billboard showed the business mogul holding a hammer with a backdrop of Christ on a cross with a speech bubble that says: "I don't like losers."

"For those of us at St Luke's, the cross is about politics. Jesus was killed – violently, publically and shamefully – because he spoke truth to power and confronted the leaders of his day about their treatment of the outcasts," Minister Glynn Cardy explained.

He added that the billboard will remain all through Easter to underscore the church's disapproval of Trump's offensive and racist comments.

The church pastor said Trump's attitude of seeing winners as only those who have money and power and his dismissal of people like Jesus, who associated with the oppressed, is very saddening.

"I hope that voters in the US will see Trump's message for what it is, and not make him a nominee for their highest office," he said, citing the controversial candidate's statements on Muslims, women and Mexican immigrants.

Roman Catholic academics have also denounced Trump's candidacy for similar reasons.

In a recently published position on The National Reviewer, the academics criticised Trump for his vulgarity and his callous statements on race, ethnicity and gender.

"Donald Trump is manifestly unfit to be president of the United States. His campaign has already driven our politics down to new levels of vulgarity. His appeals to racial and ethnic fears and prejudice are offensive to any genuinely Catholic sensibility," the statement read.
