Reacting to the decision by the University of Glasgow, former-Moderator of the Free Church of Scotland Revd David Robertson said they should be prepared to encounter upsetting content.
Speaking on Premier's News Hour, he said: "These are meant to be university students, they're meant to be the leaders of the future, they're meant to be our intelligentsia.
"If they can't cope with basic stuff like that, then one wonders whether they should be studying it all."
According to the Daily Mail pupils studying the 'Creation to Apocalypse: Introduction to the Bible (Level 1)' module are given the disclaimers, because they watch cinematic depictions of Jesus on the cross.
The move is aimed to safeguard the wellbeing of vulnerable students.
Revd Robertson went on to say: "The biggest danger is we sanitise the Cross into something ridiculous; we have pictures of a smiling Jesus on a cross.
"The Cross was utterly horrendous; you turned your eyes away from it and we need to portray it in that way much more.
"It's almost comedic and laughable actually. I think my biggest problem with it is, 'What do you expect in the Crucifixion?'
"The Cross is going to be horrible. Are you going to Disneyfy it?"
Other universities provide warnings over some of their content material, for example veterinary or forensic science courses where students may have to look at dead animals or crime scenes.
Liz Smith, education spokesman for the Scottish Conservatives, said: "Universities are meant to be a place of learning where concepts are challenged and tricky subjects debated.
"That will become increasingly difficult if they go too far out their way to ensure everything survives the politically correct test. Some of the examples set out here are patently ridiculous."
The University of Glasgow said: "We have an absolute duty of care to all of our students and where it is felt course material may cause potential upset or concern warnings may be given."
