ONE
No one can be a Christian unless they are united to Christ invisibly, that is by the Spirit. This is the church from God’s perspective. All who are united to Christ are ONE in Him, regardless of their race, gender, age, occupation, or denominational affiliation:
1 Cor. 12:12-13, ‘For just as the body is one and has many members, and all the members of the body, though many, are one body, so it is with Christ. For in one Spirit we were all baptised into one body---Jews or Greeks, slaves or free---and all were made to drink of one Spirit.’
