Please tell me the meaning of baptized and body in 1 Corinthians 12:13
There are two Baptisms, the Believers Baptism & the Baptism of the Holy Spirit. The (believers) baptism is the act of showing the world in good conscience that we’ve died with Christ and have been buried and resurrected with Him by immersion into water. The (baptism of the Holy Spirit) is the Holy Spirit dwelling in us and leading us in the path we should be headed for the Lord. In fact placing us into the Body of Christ. Acts 11:16 Then remembered I the word of the Lord, how that he said, John indeed baptized with water; but ye shall be baptized with the Holy Ghost.
The verses you are mentioning “1st Corinthians 12:12 For as the body is one, and hath many members, and all the members of that one body, being many, are one body: so also is Christ. 12:13 For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.” are telling us that we are members of the same Body doing different tasks for the Lord.
Reading the following verses you’ll see exactly what’s meant. 1st Corinthians 12:14 For the body is not one member, but many. 12:15 If the foot shall say, Because I am not the hand, I am not of the body; is it therefore not of the body? 12:16 And if the ear shall say, Because I am not the eye, I am not of the body; is it therefore not of the body? 12:17 If the whole body were an eye, where were the hearing? If the whole were hearing, where were the smelling? 12:18 But now hath God set the members every one of them in the body, as it hath pleased him. 12:19 And if they were all one member, where were the body? 12:20 But now are they many members, yet but one body.
The letter to the Romans makes this even clearer! Romans 12:4 For as we have many members in one body, and all members have not the same office: 12:5 So we, being many, are one body in Christ, and every one members one of another. 12:6 Having then gifts differing according to the grace that is given to us, whether prophecy, let us prophesy according to the proportion of faith;
Therefore the meaning or definition of the “Body” is the Church and the Church is made up of Born Again & Baptized Believers in Christ Jesus. Does this answer your question?
