We were supposed to find any evidence of the identity of God (not a mention of the word "trinity") in the writing of 1 Clement.
Here it is:
The writing of Clement of Rome (c. 96 A. D.) to the Corinthians (1 Clement) is:
“the earliest and most valuable surviving example of Christian literature outside the New Testament” and “was widely known and held in very great esteem by the early Church. It was publicly read in numerous churches, and regarded as being almost on a level with the inspired scriptures.” - pp. 17, 22, Early Christian Writings, Staniforth, Dorset Press, New York.
Clement, St., Pope of Rome (ca. 92-101) .... St. Clement is looked upon as the first of the ‘Apostolic Fathers.’ - p. 177, An Encyclopedia of Religion, Ferm (ed.), 1945.
So what did this famous Apostolic Father tell us about the essential knowledge of God?
[In the early days of Christianity] one believed in the Father, in the Son and in the Holy Spirit, but no tie was available to unite them together. They were mentioned separately. Prayers were addressed, for example, to the Father who ‘alone,’ according to Clement of Rome, ‘was God.’ - Revue d’ Histoire et de Litterature Religieuses (Review of History and of Religious Literature), May-June, 1906, pp. 222, 223.
Yes, Clement of Rome wrote:
“[Grant unto us, Lord {Jehovah, Father}] that we may set our hope on Thy Name {Jehovah - Ps. 83:18, KJV, Ex. 3:15, NEB, LB, MLB} which is the primal source of all creation ... that we may know thee, who alone abides Highest in the lofty, Holy in the holy ... Let all the Gentiles know that Thou art God alone, and Jesus Christ is Thy Son, and we are Thy people and the sheep of Thy pasture.” - 59:2-4, The Apostolic Fathers, Lightfoot and Harmer, noted trinitarian scholars. [Information in special brackets { } added by me.]
“Jesus Christ was sent forth from God. So then Christ is from God, and the Apostles are from Christ. Both therefore came of the will of God in the appointed order.” - 42:1, 2, Lightfoot & Harmer, The Apostolic Fathers.

“The formulation ‘One God in three persons’ was not solidly established, certainly not fully assimilated into Christian life and its profession of faith prior to the end of the 4th century. But it is precisely this formulation that has first claim to the title the Trinitarian Dogma. Among the Apostolic Fathers [those very first Christians who had known and been taught by the Apostles and their disciples], there had been nothing even remotely approaching such a mentality or perspective.” - New Catholic Encyclopedia, p. 299, v. 14, 1967.
“Justin and the other Apologists therefore taught that the Son is a creature. He is a high creature, a creature powerful enough to create the world, but nevertheless, a creature. In theology this relationship of the Son to the Father is called Subordinationism. The Son is subordinate, that is, secondary to, dependent upon, and caused by the Father.” - p. 110, A Short History of the Early Church, Eerdmans (trinitarian), 1976.
