Morneau was born in 1925 in Quebec, Canada, into a family of devout French CanadianCatholics; two of his aunts were nuns, and one uncle was a priest. While he was a youth, his mother died and he experienced disillusionment in God that he later claimed stemmed from teachings in Catholic books and the Church. He claimed to have been concerned with teaching that there is no salvation outside the Roman Catholic Church, and felt he could not understand a God that would torture people eternally in hell.
As a young adult, Morneau was introduced to spiritualism through a friend, and nearly joined a secret order of spirit worshipers who claimed to be the "elite". Before he was to make a full commitment, however, he asked a Seventh-day Adventist co-worker, Cyril Grosse, to go over some Bible studies with him. This turned him away from spiritualism and began his studies of Christ as an Adventist. In defiance of a bounty on his head of $10,000 (approximately $126,000 in 2012 dollars), he became a member of the Adventist Church in 1946. In 1947, he married Hilda, a licensed vocational nurse in Montreal, after which he worked for many years in telephone advertising sales. In 1984, a virus destroyed part of his heart muscle, giving him cardiomyopathy for the rest of his life. Morneau died in 1998.
