We all know that any Baby including Jesus Christ receives / received 23 Chromosomes from their Mother. These Chromosomes / DNA stay with a baby all their adult life. In order for Jesus Christ not to be Born, having no sin, the Chromosomes can not be tainted with Sin from Mary His Mother, therefore Mary is the Immaculate Conception.
Hank, you may say what about Mary's Mother? Well, everything has its beginning in the O.T. aka Adam and Eve created without sin. So too in the beginning of N.T. there is a new beginning, The New Adam is Jesus and the New Eve, is Virgin Mary.
Hank, or do you believe that Jesus has not the Power to grant his Mother to be the Immaculate Conception???
If you say No, then to you Jesus Christ is limited with His Power and is contaminated with sin of Mary's 23 Chromosomes. If you say Yes He can do all thingssss, then believe that Mary is the Immaculate Conception. (There is no in betweens)
