Two Catholic theologians on "trinity" and "pre-existence"

This is what Edmund J. Fortman (d. 1990), a highly respected Catholic theologian wrote in his exhaustive study on the Trinity:

The formulation of this dogma was the most important theological achievement of the first five centuries of the Church ... yet this monumental dogma, celebrated in the liturgy by the recitation of the Nicene creed, seems to many even within the Church to be a museum piece, with little or no relevance to the crucial problems of contemporary life and thought. And to those outside the Church, the trinitarian dogma is a fine illustration of the absurd length to which theology has been carried, a bizarre formula of ‘sacred arithmetic.’ -- Edmund J. Fortman,  The Triune God (New York: Baker Book House, 1972, p. xiii).

This is how Catholic theologian Karl-Josef Kuschel addresses the question and cornerstone Trinitarian belief of the pre-existence of Jesus Christ:

Anyone who does not approach the New Testament with a prior concept of pre-existence moulded by the history of dogma, but listens to what the New Testament has to say on this matter, will not fail to note that the New Testament does not know of pre-existence as a speculative theme.  A pre-existence Christology understood as isolated, independent, atomized reflection on a divine being of Jesus Christ ‘in’ or ‘alongside’ God before the world, a sonship in metaphysical terms, is not the concern of the New Testament.  On the contrary, such a pre-existence Christology must be relativized in the light of the New Testament. -- Karl-Josef Kuschel, Born before all time?
