You mean the current policy and doctrine found in the recent Catechism:
838 "The Church knows that she is joined in many ways to the baptized who are honored by the name of Christian, but do not profess the Catholic faith in its entirety or have not preserved unity or communion under the successor of Peter." 322 Those "who believe in Christ and have been properly baptized are put in a certain, although imperfect, communion with the Catholic Church." 323 With the Orthodox Churches, this communion is so profound "that it lacks little to attain the fullness that would permit a common celebration of the Lord's Eucharist." 324
That doesn't sound to me like a call to slaughter those who do not share our beliefs. But I'm not an expert on Catholics like you are.

It doesn't really say anything though, does it. Unum sactum is more clear than this because this statement is made in doubletalk for appeal through ecumenism to try and bring outsiders into the Roman fold. It doesn't address the fact that UNUM SANCTUM still stands, Lateran IV still stands, the teachings on heresy still stand, the canon law regarding heresy still stands.. You should know better than to pull that with me by now Dave.
