nothing. christ has been alive forever, and will be alive for eterinity, along with God and the holy spirit, as they are all one person and three people at the same time. (this is a bit confusing. you have to think outside the box for this.) Jesus was the word, and it says in The Bible "in the beginning was the word," so jesus has always been there.
ac is After Christ and bc is Before Christ
Before Christ means Before Jesus Was Born And After Christ Means After Jesus Was Born
Before the birth of Christ
Before the birth of Christ
BC means Before Christ. Its method of calculating time.
before christ is 2000 years prior
AD = Anno Domini which means after christ BC = Before Christ which means literally before christ Therefore 30 AD isn't even before Christ, it's 30 years after.
before Christ
It means Before Christ. (Christ was born in the year 0). BC stands for Before Christ. So 1000BC is 1000 years Before Christ was born
It depends whether it is BC or AD If it was BC it was 1200 years before Christ If it was AD it was 1200 years after Christ
I believe it means Before
long after
