The Holy Spirit will guide us into all truth of Jesus lied when He said that.
Don’t you believe the words of Jesus?
Funny, the Presbyterian in my example will claim to be led by the Holy Spirit. as will the Baptist. the Mormons, Methodists, Jehovah Witnesses, Oneness Pentecostals, Lutherans, Anglicans, 7th Day Adventists and the Nazarenes also all claim to be led into truth by the Holy Spirit.
the truth is a person, Jesus Christ. the Holy Spirit is not the author of confusion, nor can He lead someone to believe something in the 1st century and then lead someone to believe the opposite in the 16th century. so unless you claim infallibility, you have no assurance you personally will be led to truth by the Holy Spirit.
so how does the Holy Spirit lead us to truth? the answer to that is the same now as it was in the year 50ad....thru The Church.
it is the Holy Spirit that raises up leaders in the Church, it is the Holy Spirit that guides and protects the Church.
it is the Church that Jesus gave authority to make disciples of all nations, baptizing them and TEACHING them.
no one in the Scriptures was ever instructed to read the Scriptures and decide for themselves what they mean.
in fact, quite the opposite. The Holy Spirit sent the Church to instruct the eunuch in Acts 8.
the basis for the truth the Church proclaims also is the same today as it was in 50ad, namely the teaching of the Apostles. this Apostolic teaching was not limited to only the written word, but also included the oral teaching of ALL the Apostles.
so when we look at the doctrine of infant baptism, we look to follow the practice of the Apostles. the Scriptures are not clear when they say whole families were baptized, if those families included infants or not. but we are 100% sure the Apostles baptized infants from the Apostolic Tradition followed by the Universal Church for 2,000 years.
if one is truly going to believe the words of Jesus, one would have to believe the Church would not/could not/did not go apostate in the 2nd, 3rd or 4th century and would never need to be re-established in the 16th century.
so if one reads the Scriptures and finds a doctrine that opposes what the Church teaches, you can be sure the Holy Spirit is not the one who led you into that belief. Again, not the author of confusion.
the Holy Spirit leads true believers into unity in the faith and though we are many and cover 2,000 years, Christians are one because we all share the same Eucharist.
as further proof the continuity of the true Church, I will leave you to ponder Ephesians 3:20-21
Now to him who by the power at work within us is able to do far more abundantly than all we ask or think, to him be GLORY IN THE CHURCH AND IN CHRIST JESUS TO ALL GENERATIONS, for ever and ever. Amen.
“all generations” includes the years 95ad thru the 16th century.
Differences in governance or preferences in governance do not equate to theological differences.
Why do Catholics demand lockstep interpretation of Scripture by non-Catholics and yet don’t demand it of themselves for either Scripture or the CCC?
The individual is led into truth by the Holy Spirit. If you don’t trust Him to do the job or think He’s capable of it, then you will never be led into it and you’ll be forever without it.
