The clause does not say that. Indeed, it leaves the impression that divorcees may only receive the Eucharist "in certain circumstances."
The pastoral insensitivity in this clause is astounding, and would certainly not encourage a divorced, fallen-away Catholic to approach the Church, again.
Those certain circumstances would be the instance of mortal sin.
What in your mind would be other "certain circumstances"?
As a once divorced/quickly and validly annulled Catholic, I do have a dog in this race. I've been through the process and smell a rat.
And btw, my Mom excommunicated herself for a few years in the early 60's by marrying outside the Faith. She remarried within the Church four years later to remedy the situation, so no one need tell me I don't know "how the Church was back then."
If anyone is going to make accusations about the Church they'd had better provide some proof instead of wimpering about mean people when Catholics validly contest outright falsehoods.
