That's because they have always been against Biblical baptism, calling the practicers of it "anabaptists" and making this a crime with the death penalty. Way back in A.D. 405 and 413 they passed those laws.
Reference: See Imperatoris Theodosii codex: Book 16, Title 6 under laws 16.6.4 and 16.6.6. "No person shall resort to the crime of rebaptizing," etc.
The problem was and still is, it's not rebaptizing, but rather their infant baptisms were not actual baptism at all. So anyone who joins the church has to be baptized into it, this gets the accusation of "rebaptism" and that's just how history unfolded.
Back on thread topic, nowadays they have all kinds of bizarre doctrine such as that they worship the same false god as the Muslims and that Catholicism is the younger brother of Judaism. From this we see they have drifted very far from the truth of God. He is not a unitarian god but God in three persons and sacred, revealed unto us by his Word.
