Instead of:
“I swear that I will pay true allegiance to Your Majesty, and to your heirs and successors according to law. So help me God”?

Pledge:
"On the memory of those who have fought for a better society over generations and on behalf of those struggling today, I pledge allegiance and solidarity to the goal of political and economic democracy; to equality, emancipation and social justice for all."

Note: this is just our suggested wording - we'd love you to share a version that's personal to you!
