Agreed , if you mean heard and understood the gospel. Could also involve the conviction of the Holy Spirit.
Ephesians 1:18 The eyes of your understanding being
enlightened; that ye may know what is the hope of his calling, and what the riches of the glory of his inheritance in the saints,
19 And what is the exceeding greatness of his power to us-ward who believe, according to the working of his mighty power,
20 Which he wrought in Christ, when he raised him from the dead, and set him at his own right hand in the heavenly places,
I see no real significant distinction between tasted and eaten. Especially if you are saying one who tasted the Heavenly gift is not Born again.
Ephesians 2:8
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God
1 Peter 2:2 As newborn babes, desire the sincere milk of the word, that ye may grow thereby:3 If so be ye have
tasted that the Lord is gracious.
In 1 Peter they have tased and yet they are born again babes in Christ.
John 6:50 This is the bread which cometh down from heaven, that a man may
eat thereof, and not die.
51 I am the living bread which came down from heaven: if any man
eat of this bread, he shall live for ever: and the bread that I will give is my flesh, which I will give for the life of the world.
In John Jesus says if you eat you will live. As related to salvation what is your scriptural difference between tasting and eating?
I believe you have watered down the meaning of "partakers" here to fit your narrative. I see no way a scriptural case can be made that a partaker of the Holy Ghost cannot at the very least be born again or baptised in the Holy Spirit of course depending on ones doctrinal beliefs on the Holy Spirit.
One can be convicted and not partake!
Hebrews 3:14
For we are made
partakers of Christ, if we hold the beginning of our confidence stedfast unto the end;
1 Corinthians 10:17 For we being many are one bread, and one body: for we are all partakers of that one bread.
Colossians 1:12
Giving thanks unto the Father, which hath made us meet to be
partakers of the inheritance of the saints in light:
I still do not see the major distinction. you make between tasting the word and eating the word. Can you point out from scripture how you make that distinction?
The word "powers" is the Greek "dumamis" Which is special miraculous power
I believe you are close right on this one. You seem to avoid the believers participation and only speak of seeing or hearing the gifts with the exception of healing. If they heard a prophecy someone had to give it. If they experienced a healing it could have been through, prayer, the laying on of hands or just a proclamation from another believer used by the Holy Spirit.
I agree with your statement "they have experienced the miraculous working of the Holy Spirit" but I believe it refers specifically to the Gifts of The Spirit!
