The Witness of God is Greater
[Testimonia]
The distinction of persons Father, Son, and Holy Spirit. In the
[First] Letter of John: Since there are three which give testimony on earth: the Spirit, water, and the Blood; and the three are of one in Christ Jesus; and there are
three which declare a testimony in heaven, the Father, the Word, and the Spirit, and the three are one.
(Isidore of Seville,
Testimonia divinae Scripturae Chapter 2)
[Etymologiae 6.19]
43. The Greek term ‘baptism’ (baptismum, cf. βαπτισμός), is the equivalent of the Latin tinctio (“dipping,” “dyeing”) because in it a person is changed by the spirit of grace into a better thing, and is made a far different thing than he was. 44. For we were filthy before with the ugliness of sins, but in that bathing we become beautiful in the whitening of the virtues, whence it is written in the Song of Songs (8:5, in an older version), “Who is this that cometh up whitened?” 45. The mystery of baptism is not completed unless one is named, accompanied by
the naming of the Trinity, that is, of the Father, Son, and Holy Spirit, as the Lord said to the apostles (Matthew 28:19), “Go, teach ye all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit.” 46. Thus, just as
every statement is confirmed by three witnesses, so the threefold number of divine names confirms this sacrament.
(Isidore of Seville,
Etymologiae 6.19.43-46)
Is this the tria unum text given by Grantley? - Nope
Latin: [43] Baptismum Graece, Latine tinctio interpretatur; quae idcirco tinctio dicitur, quia ibi homo
spiritu gratiae in melius inmutatur, et longe aliud quam erat efficitur. [44] Prius enim foedi eramus
deformitate peccatorum, in ipsa tinctione reddimur pulchri dealbatione virtutum; unde et in Canticis
scribitur canticorum (8,5): 'Quae est ista quae ascendit dealbata?' [45] Cuius mysterium non aliter nisi
sub Trinitatis designatione, id est Patris et Filii et Spiritus sancti, cognominatione conpletur,
dicente Domino ad Apostolos (Matth. 28,19): 'Ite docete omnes gentes, baptizantes eos in nomine
Patris et Filii et Spiritus sancti.' [46] Sicut enim in tribus testibus stat omne verbum, ita hoc
sacramentum confirmat ternarius numerus nominum divinorum. (Isidore of Seville, Etymologiae
6.19.43-46; Migne Latina, PL 82.256)

Comment:
[Scopio Maffei] The next is a collection of ‘Testimonia divinae Scripturae’ from an ancient hand and there are
many indications that this was the work of St. Isidore of Spain. (Scoipione Maffei, Cassiodorii Complexiones Catholicis Dogmatibus Egregie Concinere, 1742; Translated by Jeroen Beekhuizen, correspondence, 17 February 2020.) Latin: In altero Testimonia divinae Scripturae ab antique manu coacervata sunt S. Isidori Hispalensis Iaborem suisse, plura indicia comprobant. (Scoipione Maffei, Cassiodorii Complexiones Catholicis Dogmatibus Egregie Concinere, 1742, p. 175)

Faustino Arévalo [editor of S. Isidori Hispalensis episcopi Hispaniarum Doctoris Opera omnia, denuo correcta et aucta, ed. Faustino Arévalo, 7 vols, Rome: 1797-1803] is
likely to be right when he attributes the Testimonia divinae scripturae et patrum to Isidore of Seville; and we are not surprised to find the Comma Johanneum with him [Isidore] since we have encountered it at so many of his countrymen.
