To be IN Jesus you MUST be "IMMERSED into him"!
You reject Baptism as only symbolic! You reject what CHRISTIANS have always believed for Man Made Traditions!
The Didache
“After the foregoing instructions, baptize in the name of the Father, and of the Son, and of the Holy Spirit, in living [running] water. If you have no living water, then baptize in other water, and if you are not able in cold, then in warm. If you have neither, pour water three times on the head, in the name of the Father, and of the Son, and of the Holy Spirit. Before baptism, let the one baptizing and the one to be baptized fast, as also any others who are able” (Didache 7:1 [A.D. 70]).
Hermas
“‘I have heard, sir,’ said I [to the Shepherd], ‘from some teacher, that there is no other repentance except that which took place when we went down into the water and obtained the remission of our former sins.’ He said to me, ‘You have heard rightly, for so it is’” (The Shepherd 4:3:1–2 [A.D. 80]).
Justin Martyr
“As many as are persuaded and believe that what we [Christians] teach and say is true, and undertake to be able to live accordingly . . . are brought by us where there is water, and are regenerated in the same manner in which we were ourselves regenerated. For, in the name of God, the Father and Lord of the universe, and of our Savior Jesus Christ, and of the Holy Spirit, they then receive the washing with water. For Christ also said, ‘Except you be born again, you shall not enter into the kingdom of heaven’ [John 3:3]” (First Apology 61 [A.D. 151]).
Tatian the Syrian
“Then said Jesus unto them, ‘I have been given all authority in heaven and earth; and as my Father has sent me, so I also send you. Go now into all the world, and preach my gospel in all the creation; and teach all the peoples, and baptize them in the name of the Father and the Son and the Holy Spirit’ [Matt. 28:18-19]” (The Diatesseron 55 [A.D. 170]).
Hippolytus
“When the one being baptized goes down into the water, the one baptizing him shall put his hand on him and speak thus: ‘Do you believe in God, the Father Almighty?’ And he that is being baptized shall say: ‘I believe.’ Then, having his hand imposed upon the head of the one to be baptized, he shall baptize him once. Then he shall say: ‘Do you believe in Christ Jesus . . . ?’ And when he says: ‘I believe,’ he is baptized again. Again shall he say: ‘Do you believe in the Holy Spirit and the holy Church and the resurrection of the flesh?’ The one being baptized then says: ‘I believe.’ And so he is baptized a third time” (The Apostolic Tradition 21 [A.D. 215]).
