Thank you Deacon Christopher, my faith is rock solid. I had a very deep encounter with God and conversion experience many decades ago and have been faithful ever since. I am not talking about getting into heated discussions but when non-Christians have genuine questions I want to be able to answer them accurately in words they can understand. These are people who, as you say, don’t know God yet so they are highly unlikely to pick up a bible or catechism. Instead they are asking me so I want to do my best to answer.
I find it is not uncommon that the image of God they think we believe in is not accurate. So I want to be able to correct, kindly, and use straightforward non-religious language to explain.
Before I was a Christian the following meant nothing to me. I had never heard these words:
Holy Spirit
Trinity
Eucharist
Communion
Sacrament
Just to give you an idea and there are plenty more! So I appreciate where atheists are coming from.
