Answer 1

***Did Tertullian teach that the trinity is not eternal? ***

Yes,

We find, however, that throughout history prominent trinitarians have interpreted their own doctrine in a way that subordinates Jesus Christ or makes him inferior. Tertullian, the first prominent exponent of trinitarianism, taught that the Son was subordinate to the Father and that the trinity is not eternal. [Heick, I, 127.] He taught that the Son did not exist as a separate person in the beginning, but was begotten by the Father to accomplish the creation of the world. Furthermore, Tertullian held that the distinction of persons would cease in the future. Origen, the first great proponent of trinitarianism in the East, also saw the Son as subordinate to the Father in existence and he even maintained that prayer should be addressed to the Father alone. [Heick, I, 117-118.] Both men meant the deity of Christ when they used the term Son. It can, therefore, be said that trinitarianism began as a doctrine that subordinated Jesus to God.

Have a pleasant day.

Answer 2

Why would you teach that God the Father is eternal, God the Son is eternal, and God the Holy Spirit is eternal, but the Trinity isn't? Not being familiar with Tertullians teaching I can only guess, but my guess is it's unlikely.
I thought God was the same yesterday, today, and always?
