It's heretical to teach that by baptism, non- Catholics become part of the same spiritual family as Catholics.

Catholicism for Dummies, Page 11: "The practice of attending what's called the Vigil Mass - the Saturday evening Mass, wasn't universally allowed until 1983. The rationale for this relatively new practice is that in the Jewish tradition, after sundown means the next calendar day, so Mass celebrated after sundown on Saturday evening can count for a Sunday obligation."

Throughout its history, the Catholic Church has only considered Sunday attendance sufficient for the weekly holy day of obligation. However, in 1983, this was changed by the arch - apostate John Paul II.

The Catholic Church does not permit any of the observances of the Old Law of Judaism to be religiously followed. Therefore, those that think that Saturday Mass is equal to Sunday for the weekly Mass obligation are following Judaism.

The Council of Florence condemned those who followed the religious practices of Judaism.


Pope Eugene IV, Council of Florence, 1441, ex cathedra: "The Holy Roman Church firmly believes, professes and teaches that the matter pertaining to the Law of the Old Testament, the Mosaic law, which are divided into ceremonies, sacred rites, sacrifices, and sacraments. . . after Our Lord's coming . . . ceased, and the sacraments of the New Testament began . . . All therefore, who after that time ( the promulgation of the Gospel ) observe circumcision and the Sabbath and the other requirements of the law, the holy Roman Church declares alien to the Christian faith and not in the least bit fit to participate in eternal salvation."


Catholicism for Dummies, Page 94: . . ."Catholicism doubts the Baptism in the following faith communities to be a valid sacrament: Christian Scientists, Quakers, Salvation Army, Jehovah Witnesses, Unitarians and Mormons ( Church of Jesus Christ of Latter Day Saints ). The reason has nothing to do with the religions themselves or their members, because all espouse a true love of God and neighbor.

The reason merely has to do with what Catholicism considers to be a valid sacrament."
The heretical sects they mention here do not espouse a true love of God. Notice how even any mild criticism of a non - Catholic religion is repudiated by the authors. This is consistant with the complete ( and often shocking ) religious indifferentism seen throughout the book.

Catholicism for Dummies, Page 94.: "So through Catholic Baptism, a Christian's immediate spiritual family is God the Father, Jesus, God's son and a brother to all, and Mary, the Mother of Jesus and a mother to all. And everyone who was, is, or ever will be baptised becomes their extended spiritual family. Catholics believe that Baptism makes all people brothers and sisters in Christ, whether they're Catholic, Protestant or Orthodox." 

It's heretical to teach that by baptism, non- Catholics become part of the same spiritual family as Catholics. True Catholics are only united to other Catholics by baptism. To be part of the same spiritual family is to be part of the same Church.

This would mean that non- Catholics are part of the true Church. All in the Catholic Church have the same faith and baptism. Non- Catholics do not have the same faith as Catholics and they are therefore not part of the same spiritual family.

Pope Leo XIII, Satis Cognitum (#9), June 29, 1896: "The practice of the Church has always been the same, as shown by the unanimous teachings of the Fathers, who were wont to hold as outside the Catholic communion, and alien to the Church, whoever would recede in the least degree, from any point of doctrine proposed by her authoritive Magisterium."
