[2] That 'signs' were testifications that a thing is the truth (veritas) is plain further from these:-

The disciples said to Jesus, What sign doest Thou, that we may believe Thee? what dost Thou work? John vi 30-33.

The Jews, Scribes and Pharisees, were seeking a sign from the Lord, that they might know that He was the Christ Matt. xii 38-40; xvi 1-4; Mark viii 11, 12; Luke xi 16, 29, 30; John ii 16, 18, 19.

besides elsewhere, as Isa. xlv 11, 13; Jer. xxxii 20, 21; Ezek. iv 3; Ps. lxv 8, 9 [H.B. 7, 8]; Ps. lxxviii 42, 43; Exod. vii 3; Num. xiv 11, 22; Deut. iv 34; xiii 1-3 [H.B. 2-4]; Judg. vi 17, 21; Sam. ii 34; xiv 10; Mark xvi 17, 18, 20; Luke ii 11, 12, 16. Similar things are signified by the sign of the covenant (Gen. ix 13; xvii 11; Ezek. xx 12, 20). [3] From these passages it can be seen clearly that by the 'great signs' which the beast of the dragon 'does' are not understood signs, but testifications by them that the things that they teach are true. For every heretic who has confirmed himself in untruths, after the confirmation protests that his untruths are true; for then he no longer sees truths, inasmuch as the confirmation of untruth is the denial of truth, and truth denied loses its light. And in so far as untruths shine by virtue of the light of confirmation, which is a fatuous light, so far the light of truth becomes dense darkness, as may be seen above (n. 566).
