Your depiction of the pope's universalism is untruthful.
Here's what Dominus Iesus says: " Not infrequently it is proposed that theology should avoid the use of terms like “unicity”, “universality”, and “absoluteness”, which give the impression of excessive emphasis on the significance and value of the salvific event of Jesus Christ in relation to other religions. In reality, however, such language is simply being faithful to revelation, since it represents a development of the sources of the faith themselves. "
“It is precisely this uniqueness of Christ which gives him an absolute and universal significance whereby, while belonging to history, he remains history's centre and goal: ‘I am the Alpha and the Omega, the first and the last, the beginning and the end' (Rev 22:13)”.
Above all else, it must be firmly believed that “the Church, a pilgrim now on earth, is necessary for salvation: the one Christ is the mediator and the way of salvation; he is present to us in his body which is the Church. He himself explicitly asserted the necessity of faith and baptism (cf. Mk 16:16; Jn 3:5), and thereby affirmed at the same time the necessity of the Church which men enter through baptism as through a door”.
Dominus Jesus was an exercise in back-tracking--which is why it created such a stir. You guys drive me nuts. You come up with nice quotes. But for every nice quote, I can cite ten that make the contrary point. Here are a few:
“The finite, human categories of time and space are almost completely secondary. All men, from the beginning of the world until its end, have been redeemed by Christ and his cross.” (Sign of Contradiction, 1979)
“Christians and Muslims...Both of us believe in one God...and we know that after the Resurrection he will be satisfied with us, and we know that we will be satisfied with him.” (Invitation to Joy, 1996)
“The Redemption even brings salvation to all, for each one is included in the mystery of the Redemption and with each one Christ has united himself forever through this mystery.” (Redemptoris Missio, 1990)
