Saved WithOut The Holy Ghost ?

[Scott Hutchinson]

I might be posting this in the wrong area and if so please forgive me.
I understand some Pentecostal groups and some here on AFF ,believe one is saved and then filled with The Holy Ghost.Evidently a fair amount of OPs teach this.
Now this is asked in charity, but I do read scriptures that say without the Spirit of Christ you can't be His,or none of His Or I read verses that say it is by One Spirit we are baptized into one body.

Ok what is the difference in receiving the Holy Ghost and being baptized with The Holy Ghost ?Isn't terms like being filled with The Holy Spirit and such synonymous terms for the same experience.
If regeneration is a work of the Holy Spirit how can one be regenerate with the Spirit of Christ ?

Also doesn't receiving the Spirit comes after repentance and not at repentance I understand.Because doesn't ACTS.2:37,38 teach that the Holy Ghost comes after repentance.

So can one be saved and not have the Holy Ghost or Holy Spirit ?

I am open-minded and willing to hear other's views on this subject.
