Religious legalism often creeps in sideways, in the form of suggestions. Such as, “It’s one thing to be part of the Body of Christ (the Church) but another thing again to be part of the Bride.” The suggestion is that those who are members of the Body are ordinary but those who are part of the Bride are special. But there’s no difference. It’s a matter of which metaphor best suits the context of the NT writer.
Figuratively speaking, the Church is a Body in the way its members work together. But it is also a Bride in its purity and its preparation for Jesus, its coming Bridegroom. Then again, the church is the Temple of the Holy Spirit.
Whoever succeeds in leading you to believe that one is not only better or even best but only will then separate you from the mainstream of Christianity and into a cultish backwater. In Romans 12:2 the Apostle Paul writes of “that good, and acceptable, and perfect will of God”. Some have tried to lead me to believe that God’s Will has three levels: “good” for beginners, “acceptable” if you’re progressive and “perfect” if you’ve made the grade. But Paul is using a Hebraism, which is a way of describing the same thing three ways.
Doing this is much like a husband telling his wife that she is “lovely, and beautiful, and delightful”. Such cumulative words would go down well. Paul writes of such teachers: “These people may be paying you a lot of attention, but it isn’t for your good. They only want to keep you away from me, so you will pay them a lot of attention.” (Galatians 4:17 — Contemporary English Version.)
“Beware of Greeks bringing gifts”? These days a Trojan Horse is more likely to be someone who suggests that they have a “higher revelation” or some other thing that you appear to lack. The truth is that there is only one Church and whichever way the NT describes it fits the particular aspect the inspired writer is portraying in a word picture. So just say “No thanks!” as you would to any huckster who is trying to sell you something you don’t need, and walk on by.
