Letter of Arius to Eusebius of Nicomedia:
"... because the bishop [Alexander] is severely ravaging and persecuting us and moving against us with every evil. Thus he drives us out of every city like godless men, since we will not agree with his public statements: that there was “always a God, always a Son;” “as soon as the Father, so soon the Son [existed];” “with the Father co-exists the Son unbegotten, ever-begotten, begotten without begetting;” “God neither precedes the Son in aspect or in a moment of time;” “always a God, always a Son, the Son being from God himself."
This was a fundamental Christian teaching, and this was what Arius was railing against, and refusing to be silenced.
The letter goes on:
"Before he was begotten, or created, or defined, or established, he did not exist. For he was not unbegotten. But we are persecuted because we have said the Son has a beginning but God has no beginning. We are persecuted because of that and for saying he came from non-being. But we said this since he is not a portion of God nor of anything in existence... "
Letter of Arius and his followers to Bishop Alexander of Alexandria
"... he (God) begot an only-begotten Son before time and the ages, through whom he made both the ages [Heb 1:2] and all that was made; who begot him not in appearance, but in reality; and that he made him subsist at his own will, unalterable and unchangeable, the perfect creature of God, but not as one of the creatures ... "
"... but the Son, begotten apart from time by the Father, and created and founded before the ages, was not in existence before his generation, but was begotten apart from time before all things, and he alone came into existence from the Father. For he is neither eternal nor co-eternal nor co-unbegotten with the Father, nor does he have his being together with the Father, as some speak of relations, introducing two unbegotten beginnings. But God is before all things as monad and beginning of all. Therefore he is also before the Son ..."
The Thalia (lit. 'banquet')
"And so God Himself, as he really is, is inexpressible to all. He alone has no equal, no one similar, and no one of the same glory. We call him unbegotten, in contrast to him who by nature is begotten. We praise him as without beginning in contrast to him who has a beginning. We worship him as timeless, in contrast to him who in time has come to exist.
"He who is without beginning made the Son a beginning of created things. He produced him as a son for himself by begetting him. He [the son] has none of the distinct characteristics of God’s own being For he is not equal to, nor is he of the same being as him.
"
So there is a Triad, not in equal glories. Their beings are not mixed together among themselves. As far as their glories, one infinitely more glorious than the other. The Father in his essence is foreign to the Son, because he exists without beginning...
"... It immediately follows that, although the Son did not exist, the Father was still God. Hence the Son, not being [eternal] came into existence by the Father’s will, He is the Only-begotten God, and this one is alien from [all] others
"In brief,
God is inexpressible to the Son. For he is in himself what he is, that is, indescribable,
So that the son does not comprehend any of these things or have the understanding to explain them. For it is impossible for him to fathom the Father, who is by himself. For the Son himself does not even know his own essence, For being Son, his existence is most certainly at the will of the Father.
"
The Logos is not true God. For although he is called God, he is not true [God], But through the participation of grace, just as all others, he is called God only in name...

I shall stop quoting the
Thalia here, as it goes on to position Arius as opposed in almost every aspect of the understanding of the relation of the Dather to the Son, and the relations within the Trinity, Father Son and Holy Spirit ... so much so that it's hard to see how Arius explains this in light of the Gospel of John.
The Thalia is reconstructed from citations in documents of those contending against Arius – but we should not therefore assume they simply made stuff up, Arius was there to defend himself, and he could rightly say 'show me where I wrote that' – so the language is quite likely highly critical, but to say that words were put into his mouth is perhaps going too far, and if they were, he could refute them.
