The Apostles never advocated summoning the deceased; the bishops of liturgical (=works) denominations do. And you know that we know the soul survives death and you know what we mean when we say prayers for and to the dead, but you refuse to make the distinction even for arguments' sake.
The distinction you make is from a pagan teaching, that we do not embrace.
Among the pagan philosophers, the bios (physical) life was the core and expression of the moral imperative, the good life, and the life that ceased. The zoe was shared by man and animals. The body was, thus, central in defining life, and understanding death.
Not so in Christianity, which reverses the importance, as Christ speaks of the zoe and the spiritual zoe - the eternal life (zoe) that we participate in now and continues past the death of the bios.
The association of death with lethe (forgetfulness) and not being alert, as such, is also a pagan construct.
Christ is the Truth, and truth (aletheia) means not forgetting, remembering, not sleeping, alertness. Can one be in the presence of Christ and as lethe ?
Further, to be with Christ is to be present with God Who is love; can one be in the presence of Christ Who is love and
not love ?
The righteous will be in everlasting remembrance (Psalm 112:6) - and only God is everlasting. What is it to forget those whom God remembers ?
Prov. 10:7 We are to forget to remember ?
Do you know what we mean when we say we pray for those who have left the body ? And do you know what we mean when we attest that the Scriptures are true in action, that we do not deny that we are come
now to the heavenly Jerusalem (it's in a present tense, it is kairos not chronos), to ... "the spirits of just men made perfect (teliew/completed !). Christ tells us: be being perfected as your Father in heaven is perfect (teleios). Those just men in Hebrews - they are
already perfected, they are not in process like the rest of us. And this is where we are come to
now. We are surrounded (Hebrews 12) actively now.
I do not refuse to "make a distinction for arguments sake". You claim a distinction that is not. It is a distinction that is a continuation of Hellenistic paganism, which we have refused.
