:hmmm: I think I have to disagree with you Tim.
Though they are not the same, they are also bound together in that one cannot effectively share what one does not understand and cannot explain.
Your quote of Acts 1:8 is just fine, but even n-Cs acknowledge Matthew 28’s “Great Commission”, which says,
 Going therefore, teach ye all nations; baptizing them in the name of the Father, and of the Son, and of the Holy Ghost.  Teaching them to observe all things whatsoever I have commanded you: and behold I am with you all days, even to the consummation of the world.
We are commissioned to teach as part of this witness, and apologetics is very much a part of being able to do that.
People think that “Christian witness” is a Protestant thing but it is not. Jesus commands that we be witnesses and Paul gives his witness three times in Acts of the Apostles.***1) What my life was like before Jesus.
2) How I met Jesus
3) What my life is like now that I know Jesus. ***That is Christian witness.
Yet, Paul spends a tremendous amount of time in Acts teaching, and explaining and defending what he believes and then continues that process in his epistles, so, in context we see the need for and intermarriage of apologetics in the New Testament.
Both have a interlocking place in the New Testament and one does not exist without the other. St.,Paul was indeed a very active apologist.
Apologetics usually leads to arguments. Witnessing is not argumentative.
Unfortunately this is a generalization and untrue since we see many cases of arguments and debates occurring there in Acts.
Faith sharing can be tricky and seems to often lead to questions that any witness will need to be able to deal with. You cannot blow off the teaching aspect of Our Blessed Lord’s commission for us to share our faith. :shrug:
Recounting how our lives were before Christ makes us vulnerable; people are not defensive but see that we are weak just like them, and approachable. I have two versions of my “Witness” ready in my mind at all times. One is about 30 seconds long and another is about two minutes long. I can also tell it in more detail in about eight or ten minutes.
Are you a convert or a revert? I can do this as well but it all depends on time constraints and the person’s receptivity. Here’s My Testimony.
On more than one occasion it has prompted a phone call after a family gathering or someone quietly pulling me aside. The conversation usually starts with the other person saying something like, “I have been thinking about my life a lot lately. Can I ask you a question?”***…you shall be my witnesses in Jerusalem and in all Judea and Sama’ria and to the end of the earth. ***(Acts 1:8)Are any of you ready to be witnesses to how Jesus has changed your life?
That’s wonderful Tim! God bless you for it, but without your knowledge of apologetics, how can one answer those inevitable questions and so fulfill Our Lord’s mandate to teach them? Certainly that is one reason for RCIA, but again, we need to be well familiar with our most holy faith “being ready always to satisfy every one that asketh you a reason of that hope which is in you.” (1st Peter 3:15)
They go hand in hand and cannot be separated. Yours is a way to open a dialog, but apologetics is what will ultimately do what the Lord has commanded of us.
