Queen of Heaven
Is a title given to the virgin Mary, by the Roman Catholic 'church', it represents the RC belief that Mary was a perpetual virgin before, during and after giving birth to Jesus the Son of God.
It also represents RC belief in the' immaculate conception' of Mary, and her sin free life onto death, and her physical ascension in to Heaven, in the same manner as Jesus; as depicted in the book of Acts .
It further represents the RC view that Mary is the second Eve, the Mother of God, the Co-Redemptrix and Co-mediator with her son Jesus.
In all these things, Mary is unfairly treated as having the same salvivic powers as her son, and extraordinary influence over God the Father, an influence that is sometimes seen as equal to God the Son, and on occasions is considered to have greater influence, she also carries a persuasive influence over God the Son; our Lord Jesus.
There's no basis in Scripture to this belief, and in many ways, it's a form of blasphemy to teach such 'doctrine'. Such teaching has more in common with 'pagan' and 'occult' belief systems, and is entirely alien to Judean Christian teaching, and belief.
