Pneuma: From the Spiritual Condition of Christ to the Holy Spirit-Agent

Was the identity of the Holy Spirit as a personal agent already obvious
in the expressions of faith at the pre-literary stage of Christianity?
This book traces the evolution of the expression of the early Christian
faith in relation to the notion of <i>pneuma</i> (spirit). It shows
that, first of all <i>pneuma</i>, as long as it can be traced from three
passages in antithesis with <i>sarks</i> (1 Tim 3:16; 1 Pet 3:18,22 and
Rom 1:3-4) reflecting the Christian theology prior to the early New
Testament writings, referred to the spiritual condition to which Christ
had access as a result of his resurrection, in contrast to his previous
earthly condition. Then in a more in-depth examination of Rom 1:4 from
the angle of identifiable redactions, it continues to show how the
passage/transition from this representation of the
<i>pneuma</i>-condition to that of the <i>pneuma</i> (Spirit)
designating the Holy Spirit took place.
