In a field of wheat are there more weeds than wheat? (speaking of apostate religion)
Matthew 13:24–30
He put another parable before them, saying, “The kingdom of heaven may be compared to a man who sowed good seed in his field, but while his men were sleeping, his enemy came and sowed weeds among the wheat and went away. So when the plants came up and bore grain, then the weeds appeared also. And the servants of the master of the house came and said to him, ‘Master, did you not sow good seed in your field? How then does it have weeds?’ He said to them, ‘An enemy has done this.’ So the servants said to him, ‘Then do you want us to go and gather them?’ But he said, ‘No, lest in gathering the weeds you root up the wheat along with them. Let both grow together until the harvest, and at harvest time I will tell the reapers, Gather the weeds first and bind them in bundles to be burned, but gather the wheat into my barn.’ ”
1 John 2:19 (ESV)
19 They went out from us, but they were not of us; for if they had been of us, they would have continued with us. But they went out, that it might become plain that they all are not of us.

Arius was such a weed
“In 306, Arius, who had learnt his religious views from Lucian, the presbyter of Antioch, and afterwards the martyr, took sides with Meletius, an Egyptian schismatic, against Peter, Bishop of Alexandria. But a reconciliation followed, and Peter ordained Arius deacon. Further disputes led the Bishop to excommunicate his restless churchman, who, however, gained the friendship of Achillas, Peter's successor, was made presbyter by him in 313, and had the charge of a well-known district in Alexandria called Baucalis. This entitled Arius to expound the Scriptures officially, and he exercised much influence when, in 318, his quarrel with Bishop Alexander broke out over the fundamental truth of Our Lord's divine Sonship and substance. (See ARIANISM.)”

What is Schism?
“Schism, is perversity and is chiefly due to the heresy which forms part of it. In its other aspect and as being purely schism it is contrary to charity and obedience; to the former, because it severs the ties of fraternal charity, to the latter, because the schismatic rebels against the Divinely constituted hierarchy. Anyone becomes a schismatic who, though desiring to remain a Christian, rebels against legitimate authority, without going as far as the rejection of Christianity as a whole, which constitutes the crime of apostasy.” (http://www.newadvent.org/cathen/13529a.htm)
The Arian view dismisses Christ’s divinity with the word “begotten” this word seemingly alluring to the time when Christ was not in existence, making the man Jesus subordinate both in flesh and spirit and not of the same substance as the Father. Furthermore the Holy Spirit being the third person of the trinity is dubbed by the Arians as a type of force not a person but instead the invisible arm of God.
Arius was a professional interpreter of Holy Scripture, looked up to by his followers who quote fervently the words of the apostles and held to what they passionately attribute to as the truth. But Arius much like his view of separation between a Father and his Son, forged division in the church.
It was not in any way the authenticity of Scripture on trial in Nicene but the misinterpretation of it and the subsequent teachings that followed. The same misinterpretation of scripture we see today, now the added bewilderment of adjusting the truth to accommodate the religious heretical agenda behind a lesser god.
Remember you said it your selfPurity said:The Apostasy subject is difficult for one to objectively speak on especially if you are in the midst of it.
