The word ‘Madonna’ historically meant the Virgin Mary. Virgin Mary in real life could have been a far more flawed figure but even then that doesn’t distract her association with Christianity, especially with her son and both of them have immense staying power whereas each contemporary celebrity gets forgotten over time.
Currently, ‘Madonna’ is also the name of an otherwise blasphemous, dubious musician. She may have written ‘Like A Prayer’ but people doubt her spirituality considering her actions. She’s flawed like the real Mary but as a celebrity (and brand) she’s got a tarnished, polarising reputation.
Speaking of which, somebody dressed up as Virgin Mary singing one of Madonna’s songs and got flack for it.
