Every Christian belongs to some denomination or other, even if they call themselves "non-denominational."
a) I didn’t blame JUST catholics but all denominations as they all have peculiar rules, many of which are not Biblical. But, for example, catholics worship the dead, in particular, Mary, which is UNBiblical and God calls an abomination. They also confess their sins to the priest when we are to go directly to our God in Heaven for all of our needs. Priests are old testament which ended when Jesus Christ became our High Priest.
b)every Christian does NOT belong to a denomination as many of us only worship our God in Heaven through His Son Jesus Christ and use the Bible as our guide

I think your calling not having an organization the same as being an organization, is similar to your thinking a preacher of a 20 member group of Christians the same as the Pope.
