You don't define a thing by what it requires. You define it. It is the event that 'God was in Christ reconciling the debt of man's sin...through Christ's sin-offering.' It happened in space and time in human history. It fulfilled everything promised to Israel.
Yes, it then goes on to require many things after love has compelled the believer in it to do so willingly. The things it requires are not gospel, they are response.
Thanks for saying something of content instead of snide conclusions that dismiss conversation and relationship. I'm off to work for the day now.
