This passage could potentially be used by a Trinitarian and likely has been utilized to prop up the idea that Christ is Almighty God. It reads:
And the heaven departed as a scroll when it is rolled together, and every mountain and island were moved out of their places. And the kings of the earth, and the great men, and the rich men, and the chief captains, and the mighty men, and every bondman, and every free man, hid themselves in the dens and in the rocks of the mountains; and they said to the mountains and rocks, "Fall on us, and hide us from the face of Him that sitteth on the throne, and from the wrath of the Lamb! For the great Day of His wrath is come, and who shall be able to stand?" (21st Century KJV)
Notice the use of "His" in 6:17. But other translations contain the following lectio:
for the great day of their wrath is come; and who is able to stand? (ASV)
Either way, the verse does little to support Trinitarianism.
The NET Bible provides these remarks:
Most mss (A Ï bo) change the pronoun “their” to "his" (αὐτοῦ, autou) in order to bring the text in line with the mention of the one seated on the throne in the immediately preceding verse, and to remove the ambiguity about whose wrath is in view here. The reading αὐτῶν (autwn, "their") is well supported by א C 1611 1854 2053 2329 2344 pc latt sy. On both internal and external grounds, it should be regarded as original.
