Final answer:
In 'The Pilgrim's Progress', the religious man who ceased communication with Christian after meeting Saveself is Talkative, a character who is eventually revealed as insincere.
Step-by-step explanation:
The religious man who went on a pilgrimage until he met Saveself and stopped talking to Christian in The Pilgrim's Progress by John Bunyan is Talkative. Talkative is initially appealing due to his ability to speak eloquently about spiritual matters, but he is revealed to be shallow and insincere in his convictions. This change occurs in the story when Faithful confronts Talkative about his true nature, which leads to Talkative abandoning his association with Christian.
