I don’t believe anymore as an adult, but this was taught right away when I was a kid going to the Catholic Church. I don’t think you could find a catholic who doesn’t know what the trinity is.

It…didn’t, though; there was a schism (Macedonian) within 7 years, not 700, of Nicaea, and there were even schisms that created separate long-lasting Churches on the side rejecting the view of the part of the Church that survived in union until the Catholic/Orthodox split much sooner than 700 years (e.g., the Nestorian schism in 431 and the Church of the East which survives to this day; the Chalcedonian/Monophysite schism in 451, from which the Oriental Orthodox churches still survive, etc.)
