...they immediately start in with the divinity of Christ, and, with good reason. To be sure the subject needs to addressed with them eventually. Too often, however, it never gets past this point, and the Catholic is left frustrated.
As a former JW, allow me to make a few observations.
We tend to forget sometimes ( and this is particulary poignant with Pentecost fast approaching) that there is a third person of the Holy Trinity, the Holy Spirit.
JW's believe that the Holy Spirit is not a person at all, but rather is God's "power" or "electricity". To them, there is certainly no basis of personification.
And yet, from their own New World Transaltion (bold mine):
25 “While remaining with YOU I have spoken these things to YOU. 26 But the helper, the holy spirit, which the Father will send in my name, **that one will teach YOU **all things and bring back to YOUR minds all the things I told YOU.
12 “I have many things yet to say to YOU, but YOU are not able to bear them at present. 13 However, when that one **arrives, the spirit of the truth, **he will guide YOU into all the truth, for he will not speak of his own impulse, but what things he hears he will speak, and he will declare to YOU the things coming. 14 That one **will glorify me, because **he will receive from what is mine and will declare it to YOU.
2 As they were publicly ministering to Jehovah and fasting, the holy spirit said: “Of all persons set Bar´na·bas and Saul apart for me for the work to which I have called them.”
3 But Peter said: “An·a·ni´as, why has Satan emboldened you to play false to the holy spirit **and to hold back secretly some of the price of the field? 4 As long as it remained with you did it not remain yours, and after it was sold did it not continue in your control? Why was it that you purposed such a deed as this in your heart? You have played false, not to men, **but to God.”
As we can plainly see, there is someone that Christ is speaking about, and there is someone giving commands and being lied to. Can my "power" or "strength" be lied to? Give commands on it's own? Am I called an "it" or am I called a "him"?
When discussing the Holy Trinity with JW's, before diving into Christ's divinity, try and discuss the Holy Spirit and His personification.
With Pentecost approaching, let us pray that misguided JW's come to know the truth of "Who", not "what", the Holy Spirit is.
*Come Holy Spirit, fill the hearts of your faithful and kindle in them the fire of your love. Send forth your Spirit and they shall be created. And You shall renew the face of the earth.
O, God, who by the light of the Holy Spirit, did instruct the hearts of the faithful, grant that by the same Holy Spirit we may be truly wise and ever enjoy His consolations, Through Christ Our Lord, Amen.*
