I was in this resource under 1 John 1:7 and it seems that all the hyperlinked references are wrong. They point to the Gospel of John rather than 1 John.
See Here:
In 2:12, the term is more limited, referring to Christ as He lived on earth and gave Himself for "the brethren." In 3:23; 5:13, the exact sense is defined by what follows.
Actual names used.
(I.) His Son Jesus Christ. 1:3; 3:23; 5:20. The divine antecedent is differently described in each case, and the difference colors the phrase. In 1:23, the Father (compare John 3). In 3:23, God. In 5:20, He that is true. Thus the sonship of Christ is regarded in relation to God as Father, as God, and as satisfying the divine ideal which man is able to form. The whole phrase; His Son Jesus Christ, includes the two elements of the confessions which John makes prominent.
1. Jesus is the Son of God (4:15; 5:5).
2. Jesus is the Christ (2:22; 5:1).
The constituents of the compressed phrase are all used separately by John.
(1.) Jesus. 2:22; 5:1; 4:3 (where the correct reading omits Christ). The thought is that of the Lord in His perfect historic humanity.
(2.) Christ. 2 John 9. Pointing to the preparation made under the old covenant.
(3). Jesus Christ. 2:1; 5:6; 2 John 7. Combining the ideas of true humanity and messianic position.
In 4:15, the reading is doubtful: Jesus or Jesus Christ.
On 4:2, see note.
(4.) The Son. 2:22, 23, 24; 4:14; 5:12. The absolute relation of Sonship to Fatherhood.
(5.) The Son of God. 3:8; 5:10, 12, 13, 20. Compare His Son (4:10; 5:9), where the immediate antecedent is
ὁ Θεός
God; and 5:18, He that was begotten of God. Combination of the ideas of Christ’s divine dignity and divine sonship.
(6.) Jesus His (God’s) Son. 1:7. Two truths. The blood of Christ is available and efficacious.
(7). His (God’s) Son, His only Son. 4:9. The uniqueness of the gift is the manifestation of love.
All of these point to John's gospel, not John's epistle. Who do I contact to fix this?
