Amor, The Seventh day adventists have had various opinions on weather to partake in war.
In the great war 1914 to 18 many adventists took a non combatant stand against war but also 4000 adventists were disfellowshipped in Europe for not taking up arms which led to the formation of the SDA reform movement a church which still exists today.
In 1972 the official position concerning military service states .
'The church provides pastoral support to those who conscientiously believe they must defend and protect others as well as those who believe force should never be used and thus cannot serve in the armed forces. These issues are deeply personal and merit much thought.
The SDAs have also been well represented as chaplains in the military in the USA head of chaplains corps Rear Admiral Barry Black served for many years. In 1992 44 SDA chaplains were serving and most chaplains don't carry guns.
In 1991 8000 Adventists were serving in the US forces and 2000 participated in the gulf war.
Much to the regret of anti war Adventists soldiers have come back to welcoming applause in adventist worship services and patriotic accolades in the church publications.
I'm not sure Desmonds exact thoughts we are all influenced by others by churches and by our own experiences in life. The movie about Desmonds heroism gives some indications of his thoughts about non violence but I will not spoil the movie for you all just go to see it but be warned it's not a movie for the whole family.
