Whether spiritual relationship is contracted by baptism only?

Objections

Objection 1 : It would seem that spiritual relationship is contracted by Baptism only. For as bodily kinship is to bodily birth, so is spiritual kinship to spiritual birth. Now Baptism alone is called spiritual birth. Therefore spiritual kinship is contracted by Baptism only, even as only by carnal birth is carnal kinship contracted.
Objection 2 : Further, a character is imprinted in order as in Confirmation. But spiritual relationship does not result from receiving orders. Therefore it does not result from Confirmation but only from Baptism.
Objection 3 : Further, sacraments are more excellent than sacramentals. Now spiritual relationship does not result from certain sacraments, for instance from Extreme Unction. Much less therefore does it result from catechizing, as some maintain.
Objection 4 : Further, many other sacramentals are attached to Baptism besides catechizing. Therefore spiritual relationship is not contracted from catechism any more than from the others.
Objection 5 : Further, prayer is no less efficacious than instruction of catechism for advancement in good. But spiritual relationship does not result from prayer. Therefore it does not result from catechism.
Objection 6 : Further, the instruction given to the baptized by preaching to them avails no less than preaching to those who are not yet baptized. But no spiritual relationship results from preaching. Neither therefore does it result from catechism.
Objection 7 : On the other hand, It is written (1 Cor. 4:15): "In Christ Jesus by the gospel I have begotten you." Now spiritual birth causes spiritual relationship. Therefore spiritual relationship results from the preaching of the gospel and instruction, and not only from Baptism.
Objection 8 : Further, as original sin is taken away by Baptism, so is actual sin taken away by Penance. Therefore just as Baptism causes spiritual relationship, so also does Penance.
Objection 9 : Further, "father" denotes relationship. Now a man is called another's spiritual father in respect of Penance, teaching, pastoral care and many other like things. Therefore spiritual relationship is contracted from many other sources besides Baptism and Confirmation.
