share the gospel
To have gay sex. Termed after George Alan Rekers, a religious conservative and co-founder of the homophobic "Family Research Council", who was spotted returning from a European gaycation with a male prostitute hired from Rentboy.com. When asked to explain his conduct, Rekers said that the rent boy "let me share the gospel of Jesus Christ with him with many Scriptures in three extended sessions".
That Catholic priest was able to share the gospel with over 9000 of his altar boys.
