Why wasn't the Logos included in the Nicene Creed?

When the First Ecumenical Council was summoned by Emperor Constantine I at Nicea, in 325 CE, Eusebius of Caesarea came with his local Creed, convinced that it would be accepted, or anyway used as a basis for general Creed of the Catholic Church. Here it is: > “We believe in One God, the Father Almighty, the Maker of all things > visible and invisible. And in One Lord Jesus Christ, **the Word of > God** [***ho logos tou theou***], God from God, Light from Light, Life > from Life, Son Only-begotten, first-born of every creature, before all > the ages, begotten from the Father, by Whom also all things were made; > Who for our salvation was made flesh, and lived among men, and > suffered, and rose again the third day, and ascended to the Father, > and will come again in glory to judge the quick and dead. And we > believe also in One Holy Ghost” (Eusebius of Caesarea, Letter on the > Council of Nicaea , @ Catholic Encyclopedia – **emphasis** added) If that phrase had been included in the Nicene Creed (without any pre-existent personal overtone, but simply stating that *ho logos tou theou*, in accordance with John 1:14, "became flesh", *sarx egeneto* – the logos being an essential attribute of the One and Only God - it would have clarified the Catholic doctrine on this essential point without resorting to the unbiblical "consubstantial" (*homoousios*) Then why wasn’t the Logos included in the Nicene Creed?
