Satanist Iris Fontana opened the Kenai Peninsula Borough Assembly meeting in Soldotna, Alaska with an invocation on Tuesday

A member of the Satan Temple opened a regional Alaska government meeting by declaring 'Hail Satan', prompting about a dozen officials and attendees to walk out and sparking protests outside.

On Tuesday Satanist Iris Fontana opened the Kenai Peninsula Borough Assembly meeting with an invocation saying 'Let us embrace the impulse to eat of the Tree of Knowledge of Good and Evil' and 'It is Done. Hail Satan'.

She was the first member of the Satan Temple to share an invocation since the borough changed its invocation policy in November, allowing members of all faiths to share opening prayers, after previously denying certain religions.

'That which will not bend, must break, and that which can be destroyed by truth should never be spared as demise. It is done, hail Satan,' she said in her prayer.

However, she was not given a warm welcome and about a dozen officials and attendees walked out during her invocation and returned after she finished

But her invocation sparked outrage. As she took to the podium for the invocation several members of the Assembly and attendees walked out, refusing to take part in it.

Around 40 people rallied outside the southern Alaska borough's administration building protesting the Satan Temple and holding signs saying 'reject Satan and his works' and 'know Jesus and his love.'

Two police officers were on hand to deal with the crowd.

She was among the plaintiffs in the lawsuit litigated by the ACLU of Alaska against the borough after it approved a 2016 policy saying that people who wanted to give the invocations at the government body's meetings had to belong to official organizations with an established presence on the Kenai Peninsula.

Other plaintiffs who had been denied permission to give the invocations included atheist Lance Hunt and Jewish woman Elise Boyer.

All three were denied because they didn’t belong to official organizations with an established presence on the peninsula. They sued and the ACLU Alaska agreed to represent them, as per the Peninsula Clarion.

The seats were sparse as she shared her Satanist prayer and several attendees walked out as well. All the while about 40 protesters were outside, opposing her invocation

The Alaska Supreme Court last October ruled that the borough policy was unconstitutional and the borough government changed it in November to allow anyone to offer invocations regardless of religion.

No one is required to participate in the assembly invocations but members Norm Blakeley and Paul Fischer and borough Mayor Charlie Pierce walked out when Fontana took the stand, along with some audience members.

Assembly members are not required to attend the invocation to participate in its meetings.

Among the protesters was William Siebenmorgen, who flew to Alaska from Pennsylvania for the event.

'God will be pleased with our public prayers of reparation. We want God's blessings on America, not Satan's curses. Lucifer is the eternal loser. Let's keep him out,; he told KSRM.
