Are you aware that the ovum was not discovered until 1827? If that is true, it makes sense that this dogma was not proclaimed until 1854.
Perhaps, but if this were indeed true, I think you would only be proving my point that the early Fathers – at least, the ones I’ve quoted – did
not believe in Mary’s freedom from original sin, and that the dogma of the Immaculate Conception is a later innovation, not something handed down from the beginning.
The Fathers made no theological mistake in failing to understand the biology of conception, since it is a matter of science (and the science was simply not available to them).
Even if you wish to use science as a justification for doctrinal development, there is still insufficient reason to do so in the case of the Immaculate Conception. An embryo is the combination of sperm and egg, so wouldn’t it suffice to say that Mary provided the egg and God miraculously provided the sperm to fertilize the egg? After all, Jesus’ Y-chromosome couldn’t possibly have come from Mary. Or did the Church of 1854 not know about the Y-chromosome…in which case their promulgation of the Immaculation Conception in response to the discovery of the human ovum was
still a case of the Church’s jumping the gun
a la Galileo?
Infallibility does not mean popes and bishops are omniscient or that the Church has always explicitly proclaimed all true things. It only means that when the Church does declare, pronounce, and define a dogma she cannot be wrong.
It sounds like what you’re basically saying, then, is that the Church has the unilateral right to declare, pronounce, and define any dogma it wants, regardless of whether that dogma was held by the Church from the very beginning. For example, if the Church was to declare, pronounce, and define tomorrow that not only Mary but also Joseph was bodily assumed into heaven at death, then even though there is no evidence from Scripture or any writings of the Fathers to support such a notion, it would be incumbent upon the faithful everywhere to believe this.
Our first pope, St. Peter, never mentioned the word Trinity. I guess we’ll have to strike that teaching from the books as well.
Apples and oranges. The word “trinity” is used to describe a dogma of the Church that was present from the very beginning of its existence. It’s not like some scientist came along and said, “You know, I’ve just discovered that there exist beings having multiple persons,” and then the dogma of the Trinity was promulgated to accommodate this. The dogma of the Trinity had
always been the teaching of the Church – it had simply not yet been described using that particular choice of word.
