From now on, at the end of the rite of reception, before signing with the cross the forehead of the child or of the children, the priest will longer say: "Magno gaudio communitas christiana te (vos) excipit," but instead: "Magno gaudio Ecclesia Dei te (vos) excipit".Read the rest here.
In practice pope Joseph Ratzinger, as a sophisticated theologian, wanted that in the baptismal rite it should be clearly said that it is the Church of God - which subsists fully in the Catholic Church - that receives those who are being baptized, and not generically the “Christian community,” a term that also signifies the individual local communities or non-Catholic confessions, like the Protestants.
The decree published in “Notitiae" specifies that Benedict XVI “benevolently established” the aforementioned variation in the course of an audience granted to the prefect of the congregation, Cardinal Antonio Cañizares Llovera, on January 28, 2013, just two weeks before the announcement of his resignation as pope.
The decree bears the date of February 22, 2013, the feast of the chair of St. Peter, and is signed by the cardinal prefect and by the secretary, Archbishop Arthur Roche. And it is said there that it went into effect on March 31, 2013, already under the reign of Pope was Francis, who evidently had nothing to object with regard to the decision of his predecessor.
