A Protestant baptism is held to be valid by the Catholic Church if given with the trinitarian formula and with the intent to baptize. However, as the ordination of Protestant ministers is not recognized due to the lack of apostolic succession and the disunity from Catholic Church, all other sacraments (except marriage) performed by Protestant denominations and ministers are not recognized as valid. Therefore, Protestants desiring full communion with the Catholic Church are not re-baptized (although they are confirmed) and Protestant ministers who become Catholics may be ordained to the priesthood after a period of study.
Protestants who want full communion with the Catholic Church do not have to be what?
re-baptized

However, Mathews' frustration with Whitehead's books did not negatively affect his interest. In fact, there were numerous philosophers and theologians at Chicago's Divinity School that perceived the importance of what Whitehead was doing without fully grasping all of the details and implications. In 1927 they invited one of America's only Whitehead experts – Henry Nelson Wieman – to Chicago to give a lecture explaining Whitehead's thought. Wieman's lecture was so brilliant that he was promptly hired to the faculty and taught there for twenty years, and for at least thirty years afterward Chicago's Divinity School was closely associated with Whitehead's thought.
