The purpose of the Christian era is to moves descendent of Adam into the family of Jesus, the "last Adam eternal father." 1Co 15:45; Isa 9:6 So, the Christian order is familial, it is about Jesus' family pleasing the Father.
This is why Jesus is the center piece of the NT Greek text. He is God's reconciliation solution for the alienated family of the first "son of God" on earth, Adam." Lu 3:38 His mission to earth carries his teachable righteous orientation originating in the righteous culture surrounding God. Conspicuously, God's realm has a familial aura of dignity wherein God is addressed lovingly as "Father" and "Abba Father." This etiquette of "Abba Father" devotion is dominant (akin to our Papa or Daddy), and is why formal name Jehovah1 is not a feature of the Christian Scriptures. Mt 23:9 The Christian narrative cast in this intimate family culture of adoration and righteousness is detail guidelines for all destined to be Christian "born anew" sons of God, resolving the absent sons of God failure by Adam. Ga 3:26; Ro 8:14, 19; Mt 5:9
This brings the importance of Jesus' emphatic dialog with Nicodemus into sharper focus. Jn 3:3-11 "Born anew" means, one receives a spiritual rebirth (sprinkled clean water...and you will be clean" and "a new heart and...new spirit" Eze 36:25-27 cleansing "from a guilty conscience." He 10:22 into the family of Jesus. Thus, ALL true disciples of Jesus receive this spiritual righteous pedigree, i.e. a born anew spirit "anointing." "Born again" and spirit "anointing" are synonymous.
The Rutherford understanding of "born again" is not just wrong, it's "evil." It's an attempt to diminish the purpose of what it means to be "born again" for ALL Christians. It seeks to reduce the unique Christian population, those with a "born again" righteous pedigree. It's a veiled defamation of "the Son;" as is the JW obsession to insert Jehovah in the NT, an attempt to cloud of the "glorification" of the Son. Jn 13:31
Bottom line: The Memorial is a celebration for ALL righteous disciples of Jesus. The "little flock" and the "great multitude" have the same righteous born anew pedigree. And, just as the 12 apostles is a fixed number, the "little flock" is a fixed number. The Father makes the call on heavenly "Levite" assignments. Mt 20:23; Mk 10:37 They are selected from among the pool of born anew righteous Christians, in the same way the apostles were selected from among born anew righteous Christians.
