If a protestant is a member of the body of Christ by a valid baptism and commits a sin such as using contraception, are they cut off from that body in the same way a catholic would be?

It depends. If some has invincible ignorance, that is they really don’t *know * that what they are doing is wrong, then they are either:
*]Not cut off from Christ or
*]They are cut off from Christ, but are forgiven after death

In order for sin to mortal, the are must be of grave matter, you must know it is wrong and you must do it with the full consent of the will. It is very possible that the second condition does not apply.

Have we been baptized by fire? Two pertinent quotes from Baha’i Writings:

**Man cannot free himself from the rage of the carnal passions except by the help of the Holy Spirit. That is why He says baptism with the spirit, with water and with fire is necessary, and that it is essential – that is to say, the spirit of divine bounty, the water of knowledge and life, and the fire of the love of God. Man must be baptized with this spirit, this water and this fire so as to become filled with the eternal bounty. Otherwise, what is the use of baptizing with material water? No, this baptism with water was a symbol of repentance, and of seeking forgiveness of sins. But in the cycle of Bahá’u’lláh there is no longer need of this symbol; for its reality, which is to be baptized with the spirit and love of God, is understood and established. **(‘Abdu’l-Bahá, Some Answered Questions, p. 92)

Wash yourselves thoroughly, O people of Bahá, from the defilement of the world, and of all that pertaineth unto it. God Himself beareth Me witness! The things of the earth ill beseem you. Cast them away unto such as may desire them, and fasten your eyes upon this most holy and effulgent Vision. (Bahá’u’lláh, quoted in The Advent of Divine Justice, p. 30)
