Taking Christ as our person? What's the meaning of person here?

[Truthseeker]

Now, HWMR talks about taking Christ as our person. That means our natural life from old person must be dealt with and replaced by Christ as new person. The problem here is if taking Christ as our person is orthodox or heretical. What does exactly mean person? If we study Triune God or Trinity theology, we will find out three persons in one God (Father, Son and Spirit). So, person in theological terms refers to a hypostate of divine Trinity.

From this, what does exactly mean taking Christ as our person according to Witness Lee and LSM's publication? Do they mean that we have to become one of divine Trinity or one of hypostate? This teaching is really orthodox or theologically correct? I feel abnormal for this teaching.
