ALL are invited to come unto Christ through baptism. There is no formal creed, catechism or confession required. By being baptized, you are not joining any organization that must approve you. Your qualification is between you and the Lord.
Jesus Christ listed the qualifications for baptism as follows:
Verily I say unto you, that whoso repenteth of his sins through your words, and desireth to be baptized in my name, on this wise shall ye baptize them—Behold, ye shall go down and stand in the water, and in my name shall ye baptize them. (3 Nephi 11:23)
I bear record that the Father commandeth all men, everywhere, to repent and believe in me.
And whoso believeth in me, and is baptized, the same shall be saved; and they are they who shall inherit the kingdom of God. (3 Nephi 11:32-33)
The Doctrine of Christ requires that you believe in Christ and repent of your sins. You therefore must be old enough to understand Christ’s Doctrine, believe in Him, and repent. (At least 8 years old.) If you meet these criteria and desire baptism, you are invited to receive it.
Wherefore, my beloved brethren, I know that if ye shall follow the Son, with full purpose of heart, acting no hypocrisy and no deception before God, but with real intent, repenting of your sins, witnessing unto the Father that ye are willing to take upon you the name of Christ, by baptism—yea, by following your Lord and your Savior down into the water, according to his word, behold, then shall ye receive the Holy Ghost; yea, then cometh the baptism of fire and of the Holy Ghost; and then can ye speak with the tongue of angels, and shout praises unto the Holy One of Israel. (2 Nephi 31:13)
And he inviteth them all to come unto him and partake of his goodness; and he denieth none that come unto him, black and white, bond and free, male and female; and he remembereth the heathen; and all are alike unto God, both Jew and Gentile. (2 Nephi 26:33)
