Formal canonisation processes are a relatively modern procedure. Saints from the earlier times were not formally canonised, but rather simply proclaimed saints by the Christian faithful. This was the case with St John the Baptist.
John the Baptist was neither beatified nor canonized.
Gabriel is an angel who was created as such in heaven by God. He had no need of canonization or beatification.
With the revised canonization process put in place by John Paul II there are now just 2 miracles required for canonization - one for beatification and then a second for canonization.
Saint Gabriel the Archangel has not been officially beatified or canonized by the Catholic Church. In Catholicism, Archangels are not typically individuals who go through the formal process of beatification and canonization like human saints do.
St. John Bosco Beatification : June 2, 1929 ( by Pope Pius XI ) canonization : April 1, 1934 ( by Pope Pius XI )
Jerrome was neither beatified nor canonized. He was declared a saint by the local Christian community shortly after he died. The canonization process was not instituted until about the 12th century
Joseph was declared a saint long before the official canonization process was instrituted by the Catholic Church. He was made a saint by popular acclaim, probably to a local bishop. Joseph was neither beatified nor canonized.
Each individual case is based on its own merits. Usually 2 miracles are required, one for beatification and one for canonization. If the person died as a martyr, one or more miracles may be dropped. Other things can also be taken into consideration such as bilocation. incorruptibility, stigmata, heavenly perfume, etc.
Saint John the Baptist has been venerated since ancient times, with the earliest recorded veneration dating back to the 4th century. His feast day, celebrated on June 24th, is an important date in many Christian traditions.
John was never officially canonized as a saint. He would have been proclaimed a saint by popular acclaim early in the history of the Church. There was no official canonization process in place at the time.
Normally, one miracle must be proven for beatification and one additional for canonization. Under extraordinary conditions(martyrdom, for example) the pope can drop one miracle from the requirement.
When a person is beatified the veneration of the sainthood candidate becomes allowable. A reliquary containing a relic of the person is prepared for the beatification ceremony and is presented to the pope during the service.
