Why does the Roman Catholic Creed include "God from God" and the Orthodox Creed does not, and does this signal any difference in dogma?

Most discussions of the Creed suggest that both the Orthodox and Roman Catholic Churches accept the Nicene-Constantinopolitan Creed and that the only substantive difference between them is the Filioque. Yet there is one other significant difference: The Catholic Creed includes "God from God" in the section on the Son of God (see ), while the Orthodox Creed does not have a similar clause (see , ). Why do they differ on whether to include this language, and does it signal any difference in dogma? NOTE: As of January 11, 2026, this question has not been answered. The discussion has provided documentation of the difference by not an explanation of why they are different.
