As https://en.wikipedia.org/wiki/Heavenly_Mother attests, there is a strong psychological appeal to a Heavenly Mother. In Egyptian mythology there is the sky goddess "Nut." In the Ascended Master Teachings (a group of religions based on Theosophy) the Heavenly Mother is called Omega. Within Mormonism there is bwelief a Heavenly Mother as the wife of God the Father. In the Unification Church some members occasionally address God as "Heavenly Mother." Within the Unification Church sometimes God is addressed as "Heavenly Mother." The Korean group World Mission Society Church of God believes that Zahng Gil Jah is the spiritual wife of God making her the heavenly new Jerusalem Mother. In Hindism there is the worship of a Mother deity. Devī (the middle name of Kamala Harris) is the Sanskrit word for "goddess." The Rigveda calls the divine female power Mahimata (R.V. 1.164.33), literally Great Mother and also called Mother Earth. In places, the Vedic literature alludes to her as Viraj, the universal mother, as Aditi, the mother of gods, and as Ambhrini, the one born of the Primeval Ocean. Durga, the wife of Shiva, is a warrior goddess who represents the empowering and protective nature of motherhood. An incarnation of Durga is Kali, who came from her forehead during war (as a means of defeating Durga's enemy, Mahishasura). Durga and her incarnations are particularly worshipped in Bengal.
Collyridianism was a heretical Christian sect that worshipped the Virgin Mary as their Heavenly Mother and as a Goddess, which the Catholic Church condemned holding that Mary was to be venerated but not adored like God - though one would be pressed to tell the difference, and indeed, Mary seems to receive more popular devotion than Christ who created her.
As said before, One would have a hard time in Bible times explaining kneeling before a statue and praising the entity it represented in the unseen world, beseeching such for Heavenly help, and making offerings to them, and giving glory and titles and ascribing supernatural attributes to such which are never given in Scripture to created beings (except to false gods), including having the uniquely Divine power glory to hear and respond to virtually infinite numbers of prayers individually addressed to them.
Moses, put down those rocks! I was only engaging in hyper dulia, not adoring her. Can't you tell the difference?
Which manner of "adulation" could constitute worship in Scripture (Words for worship in the NT (http://peacebyjesus.net/Words_used_for_worship.html)), yet Catholics imagine that by playing word games then they can avoid crossing the invisible line between mere "veneration" and worship. The Catholic Encyclopedia speculates that a further reinforcement of Marian devotion, “
was derived from the cult of the angels, which, while pre-Christian in its origin, was heartily embraced by the faithful of the sub-Apostolic age. It seems to have been only as a sequel of some such development that men turned to implore the intercession of the Blessed Virgin. This at least is the common opinion among scholars, though it would perhaps be dangerous to speak too positively. Evidence regarding the popular practice of the early centuries is almost entirely lacking...,” (Catholic Encyclopedia > Devotion to the Blessed Virgin Mary)
Yet as expected, the Catholic Encyclopedia imagines this practice came from the apostles and NT church, but which never exampled or instructed it, and instead the NT shows that the believer has immediate access to God in the Divine (http://peacebyjesus.net/DEITYofCHRIST.html) Christ, (Heb. 10:19 (http://biblia.com/bible/kjv1900/Heb.%2010.19)), who is the all sufficient and immediate intercessor between God (the Father) and man. (Heb. 2:17 (http://biblia.com/bible/kjv1900/Heb.%202.17),18 (http://biblia.com/bible/kjv1900/Heb%202.18); 4:15 (http://biblia.com/bible/kjv1900/Heb%204.15),16 (http://biblia.com/bible/kjv1900/Heb%204.16)) To the glory of God
