Final answer:
More implies that the Catholic Church is the true church of Christ by using the phrase 'Universal Church' as opposed to 'Particular Church'. This underscores the Catholic view of a single, global church and contrasts with the multiplicity of Protestant denominations.
Step-by-step explanation:
The phrase that More uses to imply that the Catholic Church is the true church of Christ is 'Universal Church' rather than 'Particular Church'. This assertion emphasizes the notion of Catholicism's global and inclusive identity, contrasting with the more fragmented approach of Protestantism, which arose from various reform movements breaking away from the Catholic Church's singular tradition and authoritative structure.
The Catholic Church has historically positioned itself as the universal church- a single, unified body which encompasses all believers and practices a singular faith. This stands in contrast to the Protestant Reformation, which generated multiple denominations each with its particular interpretation of Christianity. Both the Catholic and Protestant traditions fall under the broader umbrella of Christianity, which today includes myriad sects and interpretations of religious doctrine.
