The answer
The Coptic Church believes that the holy Theotokos was always filled with the Holy Spirit. Although she was born with the original sin, she was pure and holy all her life not having committed any personal sin.With regard to the Mystery of Baptism, one is baptized in the faith of the Church he has been baptized in.
In baptism one declares that they accept all the beliefs of this Church as their own. Being baptized in the Catholic Church means you believe in all the dogma of this Church including the Immaculate Conception, the Procession from the Son, the infallibility of the Pope, the Purgatory and other dogmas that are not acceptable in the Coptic Church. Therefore to become a member of the Coptic Church you need to be baptized in the faith of this Church. Accordingly all the Mysteries of this Church are part of her beliefs.
We believe that the Catholic Church is an apostolic Church and accept its Apostolic succession but do not acknowledge the Supremacy of the Pope of Rome.
