Full disclosure l haven't read all the posts . I am just commenting on the OP .
Most of you must know that l am Anglican, Church of England . I have never heard anyone claim that Anglicans are the Truth.
I became a Christian through some Baptists. Then l moved out of the area . My Baptist friends gave me this advice " find a church where you feel at home , where you feel that you are getting good, Biblical teaching " No mention of find your nearest Baptist church.
I have never heard any religious group ( other than Jws ) who claim to be the Truth.
