What does the wording 'Nec Tamen Consumebatur' adopted by the Church of Scotland and displayed as part of their logo mean?

Nec Tamen Consumebatur

The Latin used in the emblem created by George Mossman roughly translates into: Nec: it was not; tamen: however; consumebatur: it was consumed.

The wording refers to the Book of Exodus in the Bible when Moses encountered the burning bush. No matter how much it burned, it was never consumed by the flames. Scholars suggest that Mossman may have got the idea to use the Latin (which is the Latin of Tremellius and Junius of 1597 and not the earlier Latin of the Vulgate) from France or Holland. It is suggested that the printer deliberately used the wording in its new context to celebrate the liberation that came following the bloodless revolution of 1689 when the suffering of the Church involving the monarchy and the Covenanters was finally over.

The emblem also echoes the teachings of 16th century theologian and preacher John Calvin who saw the burning bush as representative of the people of God: the Church which suffers in any age or place but against which not even the gates of Hell can prevail.
