Grace, mercy, and peace, from
God, our Father, and Jesus Christ our Lord.
Severally is a law word.
Grace is so "MUCH MORE".
"Perfect" in Greek can be 7 things: teleios, oiktirmon, teleioo, katartizo, epiteleo, artios, pleroo.
Eg: Mt 5:48 says be teleios, but
Lk 6:36 says be (also) oiktirmon
There are also four kinds of "perfection" to consider and compare.
Hebrews 6 first talks of "leaving" things to go on unto 'teleoites' perfection
Of these two: anthropos/aner man,
No sin is imputed to aner man: Rom 4:8.
Christ is head of aner man: 1Cor 11:3.
aner man puts away childish: 1Cor 13:11
Interesting stuff to learn.
The grace of our Lord Jesus Christ [be] with you all. Amen.
