The theology is different.  You're too dense to tell the difference.  Don't take my word for it.  See what Bugnini, the principal designer of the Novus Ordo had to say about it:  " . . . We must strip from our Catholic prayers and from the Catholic liturgy everything which can be the shadow of a stumbling block for our separated brethren that is for the Protestants." (Annibale Bugnini, L'Osservatore Romano, March 19, 1965.)
