Baptism involves a pledge accepting Christ, which Trump took at the time he was baptized, in the 1970s. I don't know what the wording is in the Presbyterian Church, but the Catholic version goes as follows:
V. Do you believe in God, the Father Almighty, Creator of heaven and earth?
R. I do.
V. Do you believe in Jesus Christ, his only Son, our Lord, who was born of the Virgin Mary, suffered death and was buried, rose again from the dead and is seated at the right hand of the Father?
R. I do.
V. Do you believe in the Holy Spirit, the holy Catholic church, the communion of saints, the forgiveness of sins, the resurrection of the body, and life everlasting?
R. I do.
In order for Trump to have "recently" accepted Christ, as James Dobson alleged, Trump would have had to have renounced his earlier baptismal pledge, left the Presbyterian church, and then later changed his mind and joined some other Christian church where he once again pledged to follow Christ.
Trump maintains he has never left his faith and is "proud" to be a Presbyterian Christian and "thinks its a wonderful thing"
If I’m not mistaken, the Catholic Church accepts the Baptism of the Presbyterian Church.
The requirement is the words: “I baptize you in the name of the Father and of the Son and of the Holy Spirit.” Water can be poured over the person to be baptized one or three times or they can be “dunked” and fully covered with water.
