Unfortunately irrelevant questions help no one. Catholics are taught that God so loved mankind that He offered His own Son for suffering and crucifixion to redeem mankind.
The certainty of the infallibility of the doctrine against contraception in
Casti Connubii and in
Humanae Vitae comes from the dogma in Vatican I (post #1150), reaffirmed by Vatican II (
Lumen Gentium, 25):
“The Roman Pontiff, head of the college of bishops, enjoys this infallibility in virtue of his office, when, as supreme pastor and teacher of all the faithful – who confirms his brethren in the faith (cf. Lk 22:32) – he proclaims in an absolute decision a doctrine pertaining to faith or morals.”
Thus, no dogma has to be affirmed, nor anyone anathematized, nor the word “define” or “definition” used for an infallible papal teaching – only that the Pope is handing down a certain, decisive judgment that a point of doctrine on faith or morals is true and its contrary false.
The futility of trying to sabotage the truth which the Church proclaims is beautifully put into perspective in Post #305 by Fr Brian W Harrison in dealing with the dissenting preconceptions:

“That Onan’s unnatural act as such is condemned as sinful in Gen. 38: 9-10 was an interpretation held by the Fathers and Doctors of the Catholic Church, by the Protestant Reformers, and by nearly all celibate and married theologians of all Christian denominations until the early years of this century, when some exegetes began to approach the text with preconceptions deriving from the sexual decadence of modern Western culture and its exaggerated concern for ‘over-population.’ ”
