The first aspect of original sin is the personal sin of Adam and Eve, their disobedience to God, which caused them to Fall from grace.
At the Immaculate Conception, Mary was given the supernatural gift of complete Love for God, which is the same as complete obedience to God, and which precludes all sin…. The first aspect of the Immaculate Conception is the supernatural gift of Love/Obedience.
The second aspect of original sin is the lack of sanctifying grace. When Adam and Eve sinned, they lost the sanctifying grace that God had given them from the first moment of their creation.
The second aspect of the Immaculate Conception is sanctifying grace. The Virgin Mary had the gift of sanctifying grace from the first moment of her conception. The Virgin Mary never received the Sacrament of Baptism; her Immaculate Conception is like a more excellent form of Baptism.
The third aspect of original sin is the disorder of body and soul, wherein the soul is not directed solely toward God as our highest good and toward Heaven as our everlasting home, and wherein the body is not directed solely towards God by serving and obeying the soul.
The third aspect of the Immaculate Conception is the perfection of body and soul given to the Virgin Mary, wherein her soul was directed solely and entirely toward God, as her highest good, and toward Heaven as her everlasting home, and wherein her body was directed solely and entirely toward God by serving and obeying her soul.
The Immaculate Conception is one gift with three aspects, just as the Trinity is One God of Three Persons. The three aspects to the gift of the Immaculate Conception are: Love, Faith, Hope. Love is a reflection of the Father, Faith is a reflection of the Son, Hope is a reflection of the Spirit. Love-Faith-Hope is one gift with three aspects, just as the Father-Son-Spirit is Three Persons of One God.
The one gift (with three aspects) of the Immaculate Conception is the opposite of the one offense (with three aspects) of original sin. Thus, original sin is a negative image of the Trinity.
