UR View of the Early Church Fathers

On Emerging Universalist, Dena posed the question about the Early Church Fathers and what they believed concerning UR.  She said:

I keep hearing/reading that UR was predominantly preached/taught/believed/accepted within the realm of orthodoxy in the early church... and that it changed over once Constantine did his dirty State-Church alliancing, and once Augustine came along, ET got nailed into predominance.

I keep reading this, but I have NO resources for it... no evidence. Where can I read about this -- for I believe it would go a long way in helping to establish it as a non-heretical teaching. Does anyone have any good resources for what the early Church fathers actually wrote and taught? Any resources for the Church councils?

The first resource that came to my mind was the online writing Universalism The Prevailing Doctrine of the Christian Church During Its First Five Hundred Years. 

Following is an excerpt from the "500 year" article that talks about the Catacombs where the early Christians were buried.  There were pictures found etched on the stone wallst hat depict Christ and draped across his shoulders  there is a kid..a baby goat.  That was one of the profound things that stuck out to me when I was in the early days of searching this out.  There is the well known ET proof text that declares Jesus will send away the goats...saying get away from me....I never knew you.  So, what are we to make of these two pictures of Jesus carrying a goat on his shoulders.  That spoke volumes to me.  The excerpt and the pictures follow........

Testimony of the Catacombs.

   An illuminating side-light is cast on the opinions of the early Christians by the inscriptions and emblems on the monuments in the Roman Catacombs.¹² It is well known that from the end of the First to the end of the Fourth Century the early Christians buried their dead, probably with the knowledge and consent of the pagan authorities, in subterranean galleries excavated in the soft rock (tufa) that underlies Rome. These ancient cemeteries were first uncovered A.D. 1578. Already sixty excavations have been made extending five hundred and eighty-seven miles. More than six, some estimates say eight, million bodies are known to have been buried between A.D. 72 and A.D. 410. Eleven thousand epitaphs and inscriptions have been found; few dates are between A.D. 72 and 100; the most are from A.D. 150 to A.D. 410. The galleries are from three to five feet wide and eight feet high, and the niches for bodies are five tiers deep, one above another, each silent tenant in a separate cell. At the entrance of each cell is a tile or slab of marble, once securely cemented and inscribed with name, epitaph, or emblem. ¹³ Haweis beautifully says in his "Conquering Cross:" "The public life of the early Christian was persecution above ground; his private life was prayer underground." The emblems and inscriptions are most suggestive. The principal device, scratched on slabs, carved on utensils and rings, and seen almost everywhere, is the Good Shepherd, surrounded by his flock and carrying a lamb. But most striking of all, he is found with a goat on his shoulder; which teaches us that even the wicked were at the early date regarded as the objects of the Savior's solicitude, after departing from this life.¹³

  Matthew Arnold has preserved this truth in his immortal verse:

"He saves the sheep, the goats he doth not save!"
So rang Tertullian's sentence on the side
of that unpitying Phrygian sect which cried,--
"Him can no fount of fresh forgiveness lave,
Whose sins once washed by the baptismal wave!"
So spake the fierce Tertullian. But she sighed,
The infant Church,--of love she felt the tide
Stream on her from her Lord's yet recent grave,
And then she smiled, and in the Catacombs,
With eyes suffused but heart inspired true,
On those walls subterranean, where she hid
Her head in ignominy, death and tombs,
She her Good Shepherd's hasty image drew
And on his shoulders not a lamb, a kid!

   This picture is a "distinct protest" against the un-Christian sentiment then already creeping into the church from Paganism.
