Nope.
I am just pointing out that the abscence of a word in Scripture is no basis for rejecting a theological belief.
The word "Trinity" is not in the Bible. But, I believe in it.
The same with "rapture."
Thus, you do not agree with Sola Scriptura. The theological belief of the Trinity was developed with the aid of Tradition in the Catholic Church. It's not defined in Scripture, though present. To define it involved the weighing of traditional acceptance that such a thing (the triune God) was a reality, in spite of no explicit Biblical evidence of triunity (three persons, yes, but not triunity). Same goes for the divine/human nature of Christ. Not explicit, but defined later, with the aid of Church Tradition.
