Yes it is and I gave examples.
Note the following papal decree:
We declare, pronounce, and define that the doctrine which holds that the most Blessed Virgin Mary, in the first instance of her conception, by a singular grace and privilege granted by Almighty God, in view of the merits of Jesus Christ, the Savior of the human race, was preserved free from all stain of original sin, is a doctrine revealed by God and therefore to be believed firmly and constantly by all the faithful.
Hence, if anyone shall dare -- which God forbid! -- to think otherwise than as has been defined by us, let him know and understand that he is condemned by his own judgment; that he has suffered shipwreck in the faith; that he has separated from the unity of the Church; and that, furthermore, by his own action he incurs the penalties established by law if he should dare to express in words or writing or by any other outward means the errors he think in his heart. ...
Let all the children of the Catholic Church, who are so very dear to us, hear these words of ours. With a still more ardent zeal for piety, religion and love, let them continue to venerate, invoke and pray to the most Blessed Virgin Mary, Mother of God, conceived without original sin. Let them fly with utter confidence to this most sweet Mother of mercy and grace in all dangers, difficulties, needs, doubts and fears. Under her guidance, under her patronage, under her kindness and protection, nothing is to be feared; nothing is hopeless. ...

Ineffabilis Deus, Apostolic Constitution of Pope Pius IX on the Immaculate Conception (December 8, 1854)
The decree of the Immaculate Conception of Mary, that Mary was sinless from
her conception in
her mother's womb, is considered to be an
ex cathedra teaching, from Peter's Chair, an infallible article of faith binding on all Roman Catholics. Catholics are also taught that Mary never sinned her entire life:
411 ... Mary benefited first of all and uniquely from Christ's victory over sin:
she was preserved from all stain of original sin and by a special grace of God committed no sin of any kind during her whole earthly life.306

Catholics also teach that Jesus Christ inherited His sinless immaculate nature from His mother Mary:
... I admit we [Catholics] speak glowingly of Mary (who doesn't love and speak well of their mother?), but in this context I was being the prosaic, theological one. I wasn't using poetic, superlative language about the Blessed Virgin. I was simply laying out the logic: Jesus was the sinless Son of God.
He took his sinless human nature from his mother. For that human nature to be really human and really sinless its human source must have been uniquely pure. This seems to be a simple, logical, and modest claim.

Jesus' sinlessness is a function of his own divine nature.
I would say His sinlessness came as a direct result of the bond between Father and Son.
That's the Roman Catholic (and most everyone else's) POV. Roman Catholicism theorizes that God would have provided, in Christ's mother, a sinless being as a fitting vessel through whom the Son of God would be nurtured and born, but it is not held as anything necessary in order for Jesus to be sinless.
Not according to what was provided. Here's more:

... So much is Mary's very being full of grace that this title [Immaculate Conception] serves to identify Mary in place of her own name. It is also true that no person with a fallen nature could possess a fullness of grace, a plentitude of grace, appropriate only for the woman who was to give God the Son an identical, immaculate human nature. Mary was conceived in providence to be the woman who would give her same immaculate nature to God when God became man. Certainly we can see the fittingness in God receiving a human nature from a human mother, and receiving an immaculate nature from a truly immaculate mother.[/FONT]

... we affirm that the Second Person of the Blessed Trinity, the Word of God, who in His divine nature is from all eternity begotten of the Father, consubstantial with Him, was in the fullness of time again begotten, by be born of the Virgin, thus taking to Himself, from her maternal womb,
a human nature of the same substance with hers.
