By their message. By their statuary.
No, the person or couple needs to regularize their marriage in the Catholic Church. The Church does not recognize a civil marriage. Talk with the parish priest.
Protestant is the word that refers to a Christian that is not affiliated with the Catholic church. The protestant church includes Methodists, Presbyterians, Baptists and many other denominations.
As long as the person remains separated and does not remarry, he/she is able to receive the sacraments. The Catholic Church does not recognize divorce.
This depends on the rules of the Church into which you switch. If a person is baptized in a Protestant Christian church, and switches to the Catholic Church, he does not have to be baptized again.
The church frowns on divorce whether Catholic or not, and recognizes the protestant marriage as valid unless it is annulled. Thus the protestant, if remarried, cannot enter the catholic church unless previous marriage is annulled. If the protestant has NOT remarried, then he/she CAN enter the roman catholic faith, but cannot remarry unless previous marrige is annulled. A lot also depends on the person's previous spouse faith and form of marriage if spouse was Catholic. A sit down with priest would be advised.
"Excommunication" The Pope can "excommunicate" a person from the Catholic Church. e.g. Henry VIII was excommunicated from the Catholic Church, because he changed the Church in England to Protestant.
this person was Protestant but then turn into a Catholic
It's just Catholic, not Roman Catholic. Roman is an epithet first commonly used in England after the protestant revolt to describe the Catholic Church. It is never used by the official Catholic Church. . Confirmation is the sealing with the Holy Spirit to strengthen the person to live their baptismal promises.
One can get a divorce through legal channels but it is not recognized by the Church as the Church does not recognize divorce. The person will need to seek an annulment of the marriage through the Catholic Church. If the person were to remarry without an annulment the Church would consider the person to be living in adultery meaning the person had, in a sense, excommunicated himself from the Church and would not be eligible to receive the sacraments.
The Catholic Church does not recognize divorce. If one obtains a civil divorce the Catholic Church considers the couple as only separated. If a divorced Catholic remarries without an annulment that person is guilty of adultery and may no longer receive the sacraments.
She cannot remarry in the Catholic Church unless she has obtained an annulment or if her former spouse has passed away. The Catholic Church does not recognize divorce so if the person remarries without an annulment, she would be considered to be living in adultery.
From the Catholic point of view the person would be an apostate - one who deserts his religion for another. From the Protestant view - a convert.
