The Christian Institute has written to rugby’s national governing body calling into question its impartiality.It follows England player James Haskell saying taking an orthodox view of the Bible is a ‘road map to killing people’. So far he has received no sanction from the Rugby Football Union (RFU), but another English player – Billy Vunipola – has been disciplined for expressing Christian views. The letter follows a row over an Instagram post from Australian international Israel Folau, which resulted in him being sacked. Vunipola ‘liked’ the social media message and also posted about his Christian view that sex should be reserved for opposite sex marriage. Writing to the Head of Discipline at the RFU, Institute Director Colin Hart said: “Vunipola believes himself to have fallen short of God’s standards. He holds to mainstream Christian teaching that “all have sinned and fall short of the glory of God” (Romans 3:23).
