I saw in one of the threads that someone quoted your scriptures as saying something like “be ready to give an answer for the hope you have” and I took it to mean the ultimate truth you are relying on for salvation. So, since all of you seem to be convinced of the truth you believe it should not be too hard to explain the basis for it and how you determine its trustworthiness. If not, then maybe the elusiveness of the concept explains the heated emotions.
The reason for my hope is that God created me and Jesus died to save my soul. The Ultimate Truth, is the Trinity, Father, Son and Holy Spirit.
The FULLNESS of that Truth comes through the Holy Spirit, promised and delivered at Pentacost, through the Catholic Church which is One, Holy, Catholic and Apostolic. It is the only Church which has existed since the day the Church received the Holy Spirit and we have been assured that the “gates of hell, shall not prevail” against her.
Get out your Bible and search for Pillar of Fire, Pillar of Truth, it is about the shortest explanation of our faith available.
We have no problem defending our faith, most of us have been doing it for years.
