You don't furnish any evidence of going 'beyond Newman'. Newman is erroneously quoted by most of those who interpret him as favouring 'change' rather than 'adherence'.
Transubstantiation is a philosophical explanation of how the bread and wine are totally the Body, Blood, Soul and Divinity of Our Lord, Jesus Christ. The Church teaches that the elements of bread and wine no longer exist as realities except to our senses and that this is not dependent upon our belief, it is an objective reality whether we believe it or not. St Thomas's hymns are magnificent expositions of this doctrine.
I find revelation to be found in the Tradition of the Church. Beliefs and teachings which emanated from the early Church, the Canon of Scripture which according to Vatican II is a part of this Tradition. The various prouncements and decisions of popes and councils throughout 2 millennia and a scepticism that today's erudition is automatically superior to that of our forbears.
