G3875 names a helper, advocate, or supporting representative, often retained as Paraclete because no single English gloss carries every Johannine use. Four occurrences in Jesus' farewell discourse identify the Paraclete as the Holy Spirit or Spirit of truth. John 14:16 promises another Paraclete who will be with the disciples; John 14:26 names teaching and reminding; John 15:26 names testimony about Jesus; John 16:7 relates the Paraclete's coming to Jesus' departure and sending. First John 2:1 uses the noun for Jesus Christ as advocate with the Father when believers sin.
The phrase another Paraclete in John 14:16 does not by itself establish a technical contrast between Greek words for another, prove that the Spirit's mode of presence is identical to Jesus' incarnation, or rank the Spirit's presence as intrinsically superior to the incarnate Son. The discourse presents Father, Son, and Spirit in coordinated giving, sending, teaching, witness, and presence. Trinitarian synthesis should arise from the passages and canon rather than an etymological slogan or an overstated distinction between allos and heteros.
John 14:26 addresses Jesus' disciples and connects the Spirit's teaching with remembering what Jesus told them. It supports confidence in Spirit-enabled apostolic witness without making every private impression, prophecy claim, institutional ruling, dream, inner voice, or new teaching infallible. John 15:26 says the Spirit proceeds from the Father and is sent by the Son; the verse must not be made to settle the later filioque debate by itself. First John 2:1 opposes sin and then names Christ's advocacy. It does not portray the Father as unwilling to forgive, minimize harm, or permit deliberate sin without confession, restitution, protection, and transformed conduct.
