I posted a similar question last year but the discussion fizzled. I'm hoping someone might have additional insight for me.
I'm rereading and trying to better understand Donum Vitae. In that document, then Cardinal Ratzinger writes:
[quote=]Respect for the unity of marriage and for conjugal fidelity demands that the child be conceived in marriage; The bond existing between husband and wife accords the spouses, in an objective and inalienable manner, the exclusive right to become father and mother soley through each other.
I understand well that this is in the context of discussing the immorality of artificial reproductive technologies like IVF and surrogacy. I'm trying to understand why he chooses to say that the right of spouses to become parents exclusively through each other inalienable, as this seems to contradict the Church's tradition of facilitating and encouraging adoption.
I realize the act of adoption is an act of charity. But through the act of adoption, do not spouses become parents through someone other than each other? How does this not contradict what Ratzinger wrote?
