In Moerdijk's biblical theology, God communicates in two ways: through scripture and nature.
Moerdijk merges both methods, by using the sun in his simulation.

The Vow of the Trekkers was commemorated on 16 December as the Day of the Vow.
On 16 December, the appearance of an illuminating sun disc on the wording of the Cenotaph stone, transform their meaning as per the Philosophers Stone of the alchemists.

Instead of man below making an earthly vow, the sun shifts the focus upwards to the trinitarian god of the Trekkers, as it is God who communicates through Moerdijk's sun architecture, making Himself a heavenly vow with the words: WE - as in GOD - FOR THEE SOUTH-AFRICA.

Thus God in the trinitarian tradition of the Trekkers, speaks a vow within the sun disc illuminating the words on the Cenotaph.

The Trekker belief that God was for South Africa originates from the 9–16 December 1838 vow of Trekker leader Andries Pretorius at Blood River, who at around the same time made military and political alliances with Christian Zulus like prince Mpande.
