I would love to understand what the Universal Invisible Church teaching means from the Mennonite perspective and practice.
Is there clear Scriptural proof for the Universal Invisible Church (UIC) theology originated by Martin Luther? Am I right to understand Luther's UIC theology to mean that anyone who has first believed Christ as savior (or received first faith salvation), immediately becomes a member of the Universal Invisible Church through being 'baptized BY the Holy Spirit' into the membership of the UIC?
Would espousing this doctrine mean recognizing anyone who has first believed in Christ to have already been indwelt by the Holy Spirit, before scriptural water baptism. Is such a person already IN CHRIST or OUTSIDE OF CHRIST at this point?
Other than the account of Cornelius' and his family who received the Holy Spirit before baptism (exception to the rule), there is no other account of such. The promise of the Father (John 15:26; Luke 24:49; Acts 1:4) - the promise of the indwelling Holy Spirit was a promise specifically to the 1st church (120 members left) waiting in Jerusalem as Christ instructed them to receive the Promise. It was fulfilled on the day of Pentecost (Acts 2:33).
Those added to the church thereafter, through baptism became part of the (local) body of Christ and partook of the indwelling Holy Spirit (Acts 2:38).
If to recognize that those outside Christ already having the Spirit as per UIC theology, then what purpose would water baptism serve?
Is there a danger of causing the Lord's church to be leavened through the belief and practice of the UIC?
Let me know if the thoughts/questions above are correct or make sense, and if not, please help me out. Thank you.
