Jesus as Mother: Studies in the Spirituality of the High Middle Ages此書中，指出十二世紀天主教秘學中的「耶穌是母親」的現象。不如探討一下當中的背景是如何。
Walker Bynum此處說的是中世紀盛期的靈性，想以此來表達女權主義在古代的脈絡，他希望女權主義的歷史可以在中世紀中重構回來，他以Anselm of Canterbury作為例子。
以Anselm of Canterbury的祈禱中，我們可以看到Jesus as Mother/women的痕跡 :
"At this point that Anselm appeals to St Paul. O St Paul, where is he that was called the nurse of the faithful, caressing his sons? Who is that affectionate mother who declares everywhere that she is in labour for her sons? Sweet nurse, sweet mother, who are the sons you are in labour with, and nurse, but those whom by teaching the faith of Christ you bear and instruct? Or who is a Christian after your teaching who is not born into the faith and established in it by you? And if in that blessed faith we are born And nursed by other apostles also, it is most of all by you, for you have laboured and done more than them in all this; so if they are our mothers, you are our greatest mother."
就看上面Anselm of Canterbury有關對保羅（為父）及耶穌（為母）的表達，事實是親吻神學的典型，而事實上，大師Eriugena在9世紀，是取自奧利金及格里高里對於教會學解釋的資源（當然是他對雅歌釋經），來開始中世紀整整幾百年的神秘主義。雅歌在他來說是「信者登上聖潔寶山」，基督是母親的母親，因為母親承受分娩的痛苦在十字架上，事實上是保羅（父）演繹出來的護法，保護，孕育形象。
9-13世紀是中世紀神秘主義-隱修密契神秘主義盛行的年代，而其根源自大師Eriugena，修會的歷史不多說了，只是說，在西方修會一接觸希臘東方修會的聖像神秘傳統，Berand of Clairvaux在On the Song of Song中，以雅歌的形式，來表現他個人，與女性位格新娘的結合，而此為貞潔的結合，放諸其他當時的修士，都會此親吻神學的脈絡。
