Engagement with the Bible among Christians was obviously higher than millennials in general but only around 49% belivers said they read it more than once a month.
9% of practising Christians said they read it every day and 13% a few times a week, 13% said every week and 17% said they read it a few times a year, meaning around 51% of practising Christians read it less than once a month.
The survey was commissioned the Bible Society, designed by CODEC at the University of Durham, conducted by Comres and analysed by Barna Global.
47% all millennials asked said they haven't listened or engaged with the Bible in the last year but 29% engage with it once a month or more.
For those who had heard or read a Bible verse in the last year, which could include Christians and non-Christians, the places this primarily happened was at home (29%), at a special service, such as a wedding or funeral (22%), or at a regular church service (12%).
Special services became the most common reason to hear from the Bible once you account for only non-Christians.
The reasons for engaging with the Bible among all categories, which could include simply being at a service, were mostly 'to comfort me' (30% of those who'd read it in the last year) and 'to inspire me' (29%). Other reasons included to bring them closer to God and seeking guidance.
48% of millennials said they didn't have a relationship with the Bible.
34% said they see Bible verses shared on social media at least monthly but most said they do not pay attention to verses shared online.
About one-quarter though said the Bible verses people share online make Christianity more appealing to them.
Among the non-religious, 50% said they had neither a negative nor positive feeling towards Christianity.
