You can read from Crux the following article (simple press the title):
Excerpt: Catholics who find themselves in what the Church considers “non-legitimate” situations, such as being divorced and civilly remarried, can receive Communion as long as they want to change their situation but cannot act on their desire because doing so would lead to further sin.That’s the final word, at least according to the Vatican’s key interpreter of the law, Italian Cardinal Francesco Coccopalmerio, who was appointed by Benedict XVI in 2007 as President of the Pontifical Council for Legislative Texts.
With all due respect to Cardinal Coccopalmerio, for the Church to officially go into specific situations of pastoral concern to give guidance to bishops, priests and deacons on how to handle delicate pastoral situations is an anomaly. Dogma, doctrine and Church Canon Law must be unambiguous. The pastoral solution for complicated situations should be local but always in reference to the specific. Holy Communion based upon cheap grace isn't the Catholic way. The internal forum is no solution.
(Pandora's box is an artifact in Greek mythology, taken from the myth of Pandora's creation in Hesiod's Works and Days. The "box" was actually a large jar (πίθος pithos) given to Pandora (Πανδώρα, "all-gifted, all-giving"), which contained all the evils of the world. Pandora opened the jar and all the evils flew out, leaving only "Hope" inside once she had closed it again.)
Today the phrase "to open Pandora's box" means to perform an action that may seem small or innocent, but that turns out to have severely detrimental and far-reaching negative consequences.
No doubt, this will lead not only to the laity making up their own morality as they go, but also the clergy in their personal lives too. It is the 1970's all over except now the 1970's version of immorality of both clergy and laity will be on steroids.
The Magisterium of the Church, up until now, has always taught the ideal, the way of perfection, to be Perfect as your Heavenly Father is perfect. The Sacrament of Penance indicates that when one falls or fails to be perfect recourse to the Sacrament of Penance has no bounds if one is truly sorry and has a firm purpose of amendment.
But public sin, such a living as husband and wife when one is either not married or is in an illicit civil union brings an added burden of ceasing to give public scandal.
The Magisterium never, until now, proposes scenarios that excuses on from the clear dogmas, doctrines and Canon Laws of the Church. This is novel. In the seminary, these are discussed and solutions based upon the clear teachings of the Church are suggested.
