The husband and wife relationship is far more important than the mother son relationship and the bible is clear that in heaven we are no longer married to our earthly wives. On earth when Jesus said "Who is my mother" he puts all Christian women at the same level as Mary saying that all Christian women are His mother/sister. Therefore RC doctrine about Mary's position in Heaven is scripturally baseless.
Apples and oranges. We are collectively the Bride of Christ in the Church. Our Earthly families are types of the Heavenly Family Who is Father, Son and Holy Spirit. We have the essence of God Himself, Who is Love and from that essence, we create the physical reality of our love which is offspring. These offspring we bring to communion with Christ so that they are no longer our sons and daughters but brothers and sisters in Christ. These Earthly relationships help us understand our relationship to God... but they are not eternal.
On earth when Jesus said "Who is my mother" he puts all Christian women at the same level as Mary saying that all Christian women are His mother/sister.
Obviously. Just as He gave all Christian women on Earth to John at the foot of the Cross to care for and take as his own mother... Again, you are mixing apples and oranges. Jesus is making a point in what you cited about the Heavenly reality of doing God's Will, not a point about Earthly family.
Therefore RC doctrine about Mary's position in Heaven is scripturally baseless.
You found us out. After 2000 years and more than a billion adherents, you have discovered the truth we tried so hard to hide. Or could it be, perhaps, that this is the result of personal interpretation outside of the Christ-appointed teaching role of the Church? My money's on the latter.
