Whether spiritual relationship passes to the godfather's carnal children?

Objections

Objection 1 : It would seem that spiritual relationship does not pass to the godfather's carnal children. For no degrees are assigned to spiritual relationship. Yet there would be degrees if it passed from father to son, since the person begotten involves a change of degree, as stated above (Question [55], Article [5]). Therefore it does not pass to the godfather's carnal sons.
Objection 2 : Further, father and son are related in the same degree as brother and brother. If therefore spiritual relationship passes from father to son, it will equally pass from brother to brother: and this is false.
