All irrelevant to the discussion. Scroll down a little further in that Catholic Encyclopedia article and you will find the following statement:

"This general agreement of theologians as to papal infallibility in canonization must not be extended to beatification..."

...which is what I was saying all along.

Does that mean if most theologians think contraception is not a grave sin, it is not sinful? Do you know of any authentic magisterial documents that prove your point?

The newadvent site claims there are some who hold that beatification is infallible.
