There is absolutely no relation between baptism and going to a mikvah.
Baptism is very much needed to show you have become a changed person , and believe in christ, However it is not a Jewish ritual. It is based on the Jewish ritual of the Mikveh (מקוה), but the Mikveh is quite different. For example, If you are born into the Jewish religion, you do not need to do the Mikveh ritual. Also, The Mikveh is more than just a conversion rite. It is a used after an illness, before weddings, and after menstuation, among other things.
The sacraments that you are referring to are Christian elements. Given the nature of the celebration, Jewish people do not do this. This is a peculiarly Christian thing and is not found in Judaism.
Mikveh Israel was created in 1870.
Baptism and confirmation are both sacraments in the Christian faith that are often linked together. Baptism is typically the first sacrament received, symbolizing initiation into the Christian community and the forgiveness of sins. Confirmation is a sacrament that usually follows baptism and is seen as a strengthening of one's faith and commitment to the Christian beliefs. In some Christian denominations, confirmation is considered a completion of the initiation process that begins with baptism.
Similarites being the water baptism is a physical act and the baptism of desire is not the way that Jesus was baptized. Rather the desire is actually a desire to not have to do more than just think about baptism.
No
Yes, in Christian theology, baptism is often seen as replacing circumcision as a sign of initiation into the faith. Both practices symbolize a covenant relationship with God, but baptism is considered the New Testament equivalent in Christianity.
Ask an Orthodox rabbi.
The word mikveh in Hebrew literally means a collection. The word has come to refer to a ritual bath in which water is collected. The plural is mikvaot. A mikveh must be big enough for a person to wade into and then dunk, fully immersing his or herself. Mikvaot are used by women after their periods, by men for ritual purification, and as part of the ritual for conversion to Judaism.
There is no such thing as Jewish initiation. The mikveh is not used in a Bar Mitzva ceremony, which is the closest thing to the concept of "initiation" that I could think of. Nor is it part of a Brit (circumcision ceremony). If a non-Jew converts to Judaism, immersion in a mikveh is the final stage of the conversion. Here too, the word "initiation" has synonyms that are more apt.
In the United States, most Orthodox women, and some Conservative and fewer Reform women make a point of immersing in a Mikveh. Most Orthodox synagogues, therefore, have a Mikvah.
Christian Baptism, as I understand it, is done:1 as a one time sacrament2 as an outward expression of testimony of the believer's acceptance of Jesus' gift of salvation by his sacrificial death on the cross3 with total body immersion is symbolized the death to sin & the rising to a new life in ChristAs such, baptism is completely unrelated to the mikvah. Mikvah is a bath that an individual can go to many times throughout their lives with its purpose being to restore one's spiritual status, mikvah restores your inner pure, innocent self.
