Here is a quote that is on several catholic websites variations name him as the anti-christ
Many Catholics may wonder how come the Holy Mass and priests could be abolished... but this already happened partially at the coming of Muhammad when there were 800 Christian bishops in Africa, among them St. Augustine, and in a few years there were reduced to just 5!... the "remnant" always mentioned by Isaiah. And when Martin Luther came, in a few years millions of Christians were left without sacrifice, altar, and priests... So, this is what it will happened at the coming of the Antichrist during the Abomination of Desolation, the Holy Sacrifice of the Mass will be abolished, and consequently there will be no need for altars nor priests to celebrate it... and, of course, a "remnant" will be left!.

For many Protestants this "Abomination" means very little, because they already do not have the "perpetual sacrifice", nor "sanctuary", nor "altar", nor "priests"... The Orthodox already do not have the "prince of hosts", nor "the city".

Here a catholic website "Catholic Daily that in a round about way is calling vatican II and all the popes taht stand by it the anti-chirst http://www.dailycatholic.org/issue/2002Nov/nov25ed.htm
I found this but there was no link -- I found two version of the catholic encyclopedia on line and was not able to naviagte either wnough to say this is no or not.
QUOTE NOT MINE FROM A WEBPAGE: Catholic Encyclopedia states that Pope called Martin Luther ANTI-CHRIST, Martin Luther said POPE is the ANTI-CHRIST!!
For the moment this is the best I can do I was searching for something else when I came upon the sites saying Luther was the antichrist and the Keywords Luther and AntiChrist on Google and Yahoo are not too good to use.
the word "official" has a definite meaning within the Church, it does not refer to just the private correspondence or off-hand statements of anyone including a Pope.
I'm not surprised there was at least one pope who stated Martin Luther was the anti-Christ but that does not make it a teaching of the magisterium or a dogmatic statement. Popes say lots of things that we Catholics do not have to agree with. For instance a dogmatic statement or infallible statement by a Pope has to be in union with his brother bishops and can only concern matters of faith and morals. This has happened rarely since Vatican I.
The web pages you read are individual's opinions and have absolutely no authority in the Catholic Church.
And here is the real issue, authority. Because the Catholic Church is hierarchical and 2000 years old it has very defined ways of operating. No statement by the Pope, even the one he made which started this thread, can be taken as a dogmatic statement or a statement of belief unless certain rules are followed. As it happens, this particular statement by Benedict XVI about Sacred Scripture is just a reiteration of official Church teaching. The Church teaches that reading and knowing the Bible is important, after all it was the Catholic Church which decided which Scripture was worthy. Which Bible do you read? Even Luther's Bible was Catholic until he had his own translation made and removed certain passages he found offensive - now there's an ego for you!
In times past some wanted to translate the Bible their way, without the Catholic Church's approval, that is when the Church disapproves. At one time during the Reformation there were at least 500 translations of the Bible, some with outragious errors in them. Fortunately, even Protestant leaders objected to the worst of them and they are no longer around. Even after Henry VIII, after he broke away from the Catholic Church took issue with those who tried to translate Scripture without his approval. As I recall he didn't think it should be translated into English.
