Father is not a name but a designation.The whole family though would be called by the family name though.
Eph 3:14 ¶ For this cause I bow my knees unto the Father of our Lord Jesus Christ,
Eph 3:15 Of whom the whole family in heaven and earth is named,
hummmm what would that name be now???
Lets see what does the bible say.
First we have to be consistant.What does the bible say about the name of other gods?
Exd 23:13 And in all [things] that I have said unto you be circumspect: and make no mention of the name of other gods, neither let it be heard out of thy mouth.
Exd 34:14 For thou shalt worship no other god: for the LORD, whose name [is] Jealous, [is] a jealous God:
Now what name are we told is the only name under heaven?
Jhn 3:18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the
name of the only begotten Son of God.
Act 8:16 (For as yet he was fallen upon none of them:
only they were baptized in the name of the Lord Jesus.) Act 21:13 Then Paul answered, What mean ye to weep and to break mine heart? for I am ready not to be bound only, but also to die at Jerusalem for the name of the Lord Jesus.
Eph 1:21 Far above all principality, and power, and might, and dominion, and
every name that is named, not only in this world, but also in that which is to come:
Rev 15:4 Who shall not fear thee, O Lord, and
glorify thy name? for [thou] only [art] holy: for all nations shall come and worship before thee; for thy judgments are made manifest.
hum...what is the family name? What is that name? What name were they baptised in? Either they did not obey God and we are all up the creek for following the Apostles doctrine or the did obey what was taught them.
Either Jesus is God or there is no God.
Look at what John the Baptist said,
Mat 11:2 Now when John had heard in the prison the works of Christ, he sent two of his disciples,
Mat 11:3 And said unto him, Art thou he that should come, or do we look for another?
Mat 11:4 Jesus answered and said unto them, Go and shew John again those things which ye do hear and see:
Mat 11:5 The blind receive their sight, and the lame walk, the lepers are cleansed, and the deaf hear, the dead are raised up, and the poor have the gospel preached to them.
Mat 11:6 And blessed is [he], whosoever shall not be offended in me.
Mat 11:7 And as they departed, Jesus began to say unto the multitudes concerning John, What went ye out into the wilderness to see? A reed shaken with the wind?
Mat 11:8 But what went ye out for to see? A man clothed in soft raiment? behold, they that wear soft [clothing] are in kings' houses.
Mat 11:9 But what went ye out for to see? A prophet? yea, I say unto you, and more than a prophet.
Mat 11:10 For this is [he], of whom it is written, Behold, I send my messenger before thy face, which shall prepare thy way before thee.
Mat 11:11 Verily I say unto you, Among them that are born of women there hath not risen a greater than John the Baptist: notwithstanding he that is least in the kingdom of heaven is greater than he.
Mat 11:12 And from the days of John the Baptist until now the kingdom of heaven suffereth violence, and the violent take it by force.
Mat 11:13 For all the prophets and the law prophesied until John.
Mat 11:14 And if ye will receive [it], this is Elias, which was for to come.
Mat 11:15 He that hath ears to hear, let him hear.
