Date (happened)
6 December 1959
(probable)
"on the 6th day of December", told in Fall Love With Christ (nid 1829)
Told / reported
1968
delivery claim d0 on lecture nid=1829: 1968 exact/certain, from Neville dating his 8 April 1960 ascension as eight years earlier. A second, weaker claim d1 (1968-10, possible, state=weak) narrows to October via an unnamed remarriage read as the Onassis marriage, but that identification is speculative, so it is not used here.
Persons
Neville describes how, as each of his four mystical experiences occurred, he wrote it immediately into his Bible beside its parallel passage - the second on the 6th of December - not realising each was one of a series, and so was later able to tell them in chronological order in his book.
