I've never heard a protestant NOT "pick and choose", and I've never heard a protestant not call themselves "The Church" (capital "c")
I see it like this:
You accept Jesus as your Savior. As Pilot question the people, "What shall I do with this Jesus, whom you call Christ?"
What are YOU going to do?
Some people stress baptism. Some stress evangelism (the Great Commission). Others stress the falling of the Holy Spirit as promised by Jesus.
The Roman Catholic Club (RCc), as far as we see it, stresses attention, veneration and worship to Mary by only a less-than-handfull of verses that mention her. Despite God in the OT saying that we shall not make any graven images, the RCc's leaders have said it's ok.
Jesus told John to behold his "mother". Yet, the RCc says that John represents EVERYBODY. We don't see any evidence in the true writings of Peter, Paul and John (I say "true" because other letters, not in the Bible, have been proven false).
Jesus told Peter that "upon this rock I will build My Church". The RCc says that Peter represented just himself. Yet, in his letters, he says that we ALL are rocks and JESUS is the foundation.
Early RCc letters were proven to be false and some are forgeries. All to try to persue people to join them. Rosary beads were used to try to lure in the Hindus who used prayer beads. The "virgin" Mary and a baby Jesus was used to lure in the Pagans who had a goddess with a baby that looked just like the RCc's "Mary" and Jesus.
Even today, the RCc tried to lure in the Episcopals during the debate over homosexuality. The RCc told the Hindus "We got prayer beads, too! Join us!" and told the Pagans, "We got that, too! Join us!" and now they're saying to the Episcopals, "We are against homosexual unions, too! Join us!"
From the history of the Roman Catholic Club, we find that there is more corruption than the reign of Kwame Kilpatrick as mayor of Detroit.
It's no wonder why people have parted ways with Rome. When there's dog poop in the cookie dough, it's time to not eat their cookies and find another bakery.
