1 Corinthians 12:12,13 - Joseph Benson’s Commentary on the Old and New Testaments

For as the human body is one, and yet hath many members For different offices; and all the members, though many, constitute but one body United in one well-regulated system; so also is Christ That is, mystically considered, namely, the whole church or society, of which Christ is the head: in which, though there are several members, having different gifts, yet they do not constitute several churches, but only one church, and therefore they should all use their gifts for the good of that one. For by one Spirit When it is indeed received by us; we are all baptized into one body Are constituted true members thereof, united to the head of that body by faith, and to all the other members thereof by love: we are pardoned, regenerated, and created anew, and so made members of the true, invisible, or spiritual church; whether we be Jews or Gentiles Who are at the greatest distance from each other by nature; whether we be bond or free Slaves or freemen, who are at the greatest distance from each other by law and custom: we have all been made to drink into one Spirit In other words, The religion we before professed, whether true or false; the rank which we now hold in life, whether high or low; makes no difference as to the grand point: our union with the body, and its various members, as well as with the head, is the same, and the same happy consequences follow from that union; we all imbibe the influences of the same Spirit, by which the divine life was at first produced, and is continually preserved in our souls.
