Perhaps if you could offer the Magisterial documents pre-VII that you are referencing, and the teachings post-VII that you are addressing we can discuss.
The present teaching is that in the case of Eastern Orthodox or Oriental Orthodox, who have valid Eucharists, the Code provides that they may receive reconciliation, Communion, or the anointing of the sick “if they ask on their own for the sacraments and are properly disposed” (CIC 844 §3).
Also: Vatican II document, Orientalium Ecclesiarum # 27:
“Given the above-mentioned principles, the sacraments of Penance, Holy Eucharist, and
the anointing of the sick may be conferred on eastern Christians who in good faith are
separated from the Catholic Church, if they make the request of their own accord and are
properly disposed.”
Ut Unum Sint (# 46), May 25, 1995: “… Catholic ministers are able, in
certain particular cases, to administer the Sacraments of the Eucharist, Penance and
Anointing of the Sick to Christians who are not in full communion with the Catholic
Church…”
The previous teaching was:
Pope Gregory XVI, Commissum divinitus (# 11), May 17, 1835:
“… whoever dares to depart from the unity of Peter might understand that he no longer
shares in the divine mystery…‘Whoever eats the Lamb outside of this house is
unholy.’”
Pope Pius IX, Amantissimus (# 3), April 8, 1862:
“… whoever eats of the Lamb and is not a member of the Church, has profaned.”
