So, that means that the early Church teachings were either deficient and incomplete or that somehow the state of lesser knowldge of the world did not necessitate such teaching.

I am not a theologian, nor do I have the qualifications to address your statement. However, I see no contradiction in the catechetical preface that .... "the explanation of this revelation (no new truths have been given by anyone but Jesus) grows and develops, according to our historical time and growth in knowledge.

Scientific inquiry has necessitated a 'clarification' of religious beliefs. To cite one of the more obvious examples - abortion. The Catholic Church teaches that life must be respected from conception until natural death. We live in a society where medical science advocates contraception and has legalized abortion. The Catholic Church condemns both as interfering with the will of God.

Other christian denominations have approved the ordination of women to the priesthood. The Holy Father issued the following statement as part of an Apostolic Letter (emphasis mine):

"Wherefore, in order that all doubt may be removed regarding a matter of great importance, a matter which pertains to the Church's divine constitution itself, in virtue of my ministry of confirming the brethren (cf. Lk 22:32) I declare that the Church has no authority whatsoever to confer priestly ordination on women and that this judgment is to be definitively held by all the Church's faithful."
ORDINATIO SACERDOTALIS

The church is organic, not stagnant. The truths have always been there; occasionally, they need to be redefined for the benefit of society.

I think Kosta and I may have misunderstood the thrust of your post. There is no new revelation. The Faith is not, as the ECUSA bishops would have their beleaguered flock believe, "an evolving paradigm" where the Holy Spirit makes new revelations available to us.

To the extent that the Church is called upon to address new issues which arise (like giving communion to pro abortion politicians as is being discussed on another thread) of course the Church must make pronouncements on these things, but only in accordance with what the Church always and everywhere has believed.
