Regeneration - Broad and Narrow?

In the writings of some Calvinists and those of the Reformed dogma, such as Gill, Hodge, Shedd, etc., there is affirmation that "regeneration" may be defined in a narrow sense and in a broad sense. But, the question is - do they affirm that the scriptures use the word "regeneration" in both these ways, or do they affirm that it is theologians who use the term in both ways?

The word regeneration is only used in two places in scripture and yet none of the theologians who believe in two usages and definitions for the term confess that the two places in scripture use it in its theologically restricted sense. Thus, when they affirm that regeneration has two significations, they cannot mean that this is so with the biblical writers, but only is so with the theologians in their writings.

"And Jesus said unto them, Verily I say unto you, That ye which have followed me, in the regeneration when the Son of man shall sit in the throne of his glory, ye also shall sit upon twelve thrones, judging the twelve tribes of Israel." (Matt. 19: 28)

"Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost." (Titus 3: 5)

The former verse speaks of the regeneration of the planet, of the world, when things will be restored per the words of Peter - "until the times of restitution of all things."  (Acts 3: 21)  Paul also spoke of this:

"Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God. For we know that the whole creation groaneth and travaileth in pain together until now."  (Rom. 8: 21, 22)

The whole creation will experience a rebirth, a regeneration, a deliverance.

The latter verse speaks of regeneration as it pertains to individuals now as they are saved, washed, and renewed.  If this verse speaks of a narrowly defined regeneration, then where is the broadly defined definition of regeneration used in scripture?  If this verse speaks of a broadly defined regeneration, then where is the narrowly defined definition of regeneration used in scripture?

Even if we equate the words "born again," "begat," and "begotten" with the word "regeneration," where is there proof that these terms have both a broad and narrow definition?

Clearly there are not two definitions of regeneration or rebirth in scripture.  Thus, when theologians say that regeneration may be taken in a narrow and in a broad sense, they clearly are not referring to its usage in scripture, but to its usage by some theologians.  In fact, many of those theologians who refer to a narrow and broad definition of regeneration will nevertheless admit that the scriptures do not make such a distinction.  Further, one must be careful in reading the writings of theologians who say - "if we take regeneration in its narrow usage (by the theologians), where it refers to the first act of God or to the first principles of grace infused into the soul, then regeneration precedes faith and conversion."  Of course one could affirm that regeneration precedes faith if one defines it in such a sense.  But, that does not mean that regeneration, as it is defined in scripture, precedes faith.
