From The Apostles

Justin Martyr is an early Christian writer in Rome (150 AD), he is used to uphold several early doctrines.

In writing he does not claim he got all doctrines from the Apostles.

Baptism he says was passed down from the Apostles, he makes no such statement about the 1000 year reign of Christ. Premillinialism.

And for [water baptism] we have learned from the apostles this reason. Since at our birth we were born without our own knowledge or choice, by our parents coming together, and were brought up in bad habits and wicked training; in order that we may not remain the children of necessity and of ignorance, but may become the children of choice and knowledge, and may obtain in the water the remission of sins formerly committed. (Justin, First Apology 61)

1. Baptism of faith for the remission of sins was apostolic.

2. The 1000 year reign was opinion, and he makes no apostolic claims for it. He taught there were different opinions on the book of Revelation at that time.

Anytime we use early teachers vs the Bible we run the risk of simply making human opinion our standard.

We can say the same for Irenaeus who taught on several subjects, but taught the kingdom would begin around 500 AD. He too was pre-millinialist and made some false predictions. Most of his writings are sound but a few are clearly incorrect. His writings were not inspired though he claimed the gifts of tongues and prophecy were still with the church.

He taught some still spoke languages, thus was against the idea the entire church spoke in tongues, or that it was a universal sign of salvation as some teach today.

We have to be careful to realize that anything not from scripture may simply be opinion.

One mark of the church is she will keep the word of God through successive generations.

Isa 59:20  And the Redeemer shall come to Zion, and unto them that turn from transgression in Jacob, saith the LORD.

Isa 59:21  As for me, this is my covenant with them, saith the LORD; My spirit that is upon thee, and my words which I have put in thy mouth, shall not depart out of thy mouth, nor out of the mouth of thy seed, nor out of the mouth of thy seed's seed, saith the LORD, from henceforth and for ever.

The Holy Spirit will forever be with the church, but that doesn't mean Christ's words are dynamic and changing, the Holy Spirit supports Christ's words vs changing them.

Both the Spirit and the words will remain.

Churches that continue to change God's word while claiming to have the Spirit are imposters. Catholics who have changed God's word over time have serious problems in the judgment.
