Trinity?

Why is it, that the Father is not listed here?
Luk 12:10 And whosoever shall speak a word against the Son of man, it shall be forgiven him: but unto him that blasphemeth against the Holy Ghost it shall not be forgiven. 

So, to speak a word against the Son of man (Yeshua, who was born of a woman, a seed of Abraham, a little lower than angels, in order to taste death).

But to blasphemeth (vilify or lacking in reverence or proper respect) the holy Spirit, it shall not be forgiven.

But notice, nothing is said about speaking against the Father.
Exo 20:7 Thou shalt not take the name of the LORD thy God in vain; for the LORD will not hold him guiltless that taketh his name in vain.

Is it possible, the verse here is speaking of the Father, who is a Spirit?
Mat 10:20 For it is not ye that speak, but the Spirit of your Father which speaketh in you.
Joh 4:24 God is a Spirit: and they that worship him must worship him in spirit and in truth.
Rom 8:15 For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
Rom_8:1 There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.
Rom 8:14 For as many as are led by the Spirit of God, they are the sons of God.
1Co 6:11 And such were some of you: but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God.
Rom_8:9 But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
1Pe 1:10 Of which salvation the prophets have enquired and searched diligently, who prophesied of the grace that should come unto you: 1Pe 1:11 Searching what, or what manner of time the Spirit of Christ which was in them did signify, when it testified beforehand the sufferings of Christ, and the glory that should follow.
Gal 4:6 And because ye are sons, God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father.

Yet we have these verses:
Mat 28:19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
1Jn 5:7 For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.
1Jn 5:8 And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one.

Interestingly, in the above verse, 1Jn5:7-8
When we look at the original words here, we see this:
Holy Ghost, is the same as saying holy Spirit (pneuma= a current of air, that is, breath)
Also here:
Luk 4:1 And Jesus being full of the Holy Ghost returned from Jordan, and was led by the Spirit into the wilderness,
Holy Ghost here, is the same word as [led by the Spirit]
So, this verse is also read as:
Luk 4:1 And Jesus being full of the Holy Spirit returned from Jordan, and was led by the Spirit into the wilderness,

Just as 1Jn 5:7-8 and Mat 28:19
Mat 28:19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit:
1Jn 5:7 For there are three that bear record in heaven, the Father, the Word, and the Holy Spirit: and these three are one.
1Jn 5:8 And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one.

Did you notice though, in 1Jn 5:7-8
The Spirit is listed as bearing witness, both in heaven and Earth?
