I found this quote at forums.catholic.com
|A cluster of cells to me is no proof that life starts at conception. That cluster of cells MUST implant into the womb and THEN do I consider it a life.|
I disagree. Please see:
CONGREGATION FOR THE DOCTRINE OF THE FAITH, Instruction Donum vitae, I, 1: AAS 80 (1988), 79. says:
“Thus the fruit of human generation, from the first moment of its existence, that is to say, from the moment the zygote has formed, demands the unconditional respect that is morally due to the human being in his bodily and spiritual totality. The human being is to be respected and treated as a person from the moment of conception; and therefore from that same moment his rights as a person must be recognized, among which in the first place is the inviolable right of every innocent human being to life”.
I found this in a quotation in the recent document Instruction Dignitas Personae on Certain Bioethical Questions here:
