The most magnificent crown adorning the Christian faith and life is the doctrine of the Holy Trinity, and the brightest jewel of most precious worth atop that crown is the incarnation, resurrection, and glorification of the only begotten Son of God–Jesus the Christ, the perfect revealer of God the Father. Starting with the orthodox doctrine of the Holy Trinity acknowledging the immanent otherness of the uncreated-Creator’s Goddess, it is doctrinally essential to maintain that as the Holy Trinity exists apart from time and space creation but interacts within each dimension, so also does the Holy Trinity exist apart from the covenant but interacts with and through the Scripturally revealed covenantal pattern and practice of divine origin and design.
The relationship of the Holy Trinity to covenant theology is a deep and challenging study and like the doctrine of the Holy Trinity is sourced from the analogies of Scripture. The study of the Trinity’s connection to covenantal theology gives preeminence to Jesus Christ being the perfect revealer of God the Heavenly Father as uncreated-Creator and Savior. Acknowledging the uniquely uncreated essence–i.e. Goddess–of the Holy Trinity, nothing should be introduced or read back into the intra-Trinitarian Council that would contradict the divine non-communicable attributes of that Godness.
The many attempts to define the term “covenant” miss the main point that the Scripturally revealed Divine covenantal pattern and practice is both a structure of continuity with changing content, therefore the Biblical/theological use of the term should stand apart as covenant (informed by Scripture content and not pressed into a mold of extra-Biblical sources, e.g. Covenant with Abraham, New Covenant, Everlasting/Eternal Covenant, etc.).
Throughout much of the history of covenant theological studies, the assumption and sometimes dogma is that the intra-Trinitarian Council is essentially covenantal. The Father, Son, and Holy Spirit do not essentially relate to one another within the intra-Trinitarian Council by the Scripturally revealed covenantal pattern and practice. Concerning the intra-Trinitarian Council there is a mutual resolve of equal ultimacy without necessity, redundancy, or subordination theologically classified as the decrees of God.
The Divine decrees of creation, providence, predestination, and election issuing from the intra-Trinitarian Council superintend the compact of salvation for working out the Counsel of Peace.
