Nobody on this site would have the time to go through your friend’s site and refute every point on it…
David, I second Fidelis’ advice. However, I think we can do a bit more to help you than to simply say, “get some books and do it yourself.”
Here’s what you do. Go back to your friend and say,
“Hey, I started going through that website and I’m having trouble with some of that stuff. Can you help me to understand it?”
Then start with this one. On the first page it says that the Apostles both did and did not keep the Sabbath.
Yet, on the next page it says that they did not keep the Sabbath at all:
*However, there are some clear, objective issues I can settle for you, and one of them is whether the churches the apostles started kept the Sabbath.
The answer is no, they did not keep the Sabbath. Despite the fact that several whole books have been written arguing that they did, it is very clear they did not.*
And then you jump to Ignatius and Irenaeus? But they aren’t Apostles.
Also, you posted this verse:
Let no one judge you concerning food or drink, or in regard to a feast, new moon, or Sabbaths, which are a shadow of coming things, but the body belongs to Christ.
–Paul the Apostle, Colossians 2:16-17, c. A.D. 60
Considering the context of the times, the Jews were persecuting the Christians, St. Paul is telling the new Christians that they are not subject to the feasts, moons, or Sabbaths of the Jews.
The “shadow of things to come” is a reference to the Old Testament. In another place in Scripture, St. Paul says:
Hebrews 10:1
For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
And that is an obvious reference to the ordinances of the Old Testament which Jesus obliterated, nailing them to the Cross:
Colossians 2:14
Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;
When he gives you an answer, simply say, “ok, let me think on that a bit. I’ll get back to you.”
And come back here with the question. We can help you debunk that website the way a man eats an elephant. One bite at a time.
I hope that helps.
Sincerely,
De Maria
