Avoid them, who preach and teach against Apostles doctrine from Abraham Kutty PG's blog

Based on the following scripture, please avoid trinitarians,  or not to keep fellowship with them, who teach and preach against Apostles preached and taught.

Romans  16:17  Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them.   

Now, let's check the reasons of avoiding trinitarians. 

1. Apostles preached and taught to do baptism in the name of Jesus Christ.

However,  trinitarians give baptism in trinity, which is against Apostles doctrine. 

2. Apostles preached and taught, whatever you do by word or seed, do all in the name of Lord Jesus Christ.  Read following scripture :

Colossians  3:17 And whatsoever ye do in word or deed, do all in the name of the Lord Jesus, giving thanks to God and the Father by him.

However, trinitarians do the following against Apostles doctrine :

a) Dedication of children in trinity name.

b) Marriage ceremony in trinity name.

c) Inauguration of Conventions,  Meetings or Seminars in trinity name.

d) Laying foundation stone in trinity name.

e) Perform baptism in trinity name.

f) Benediction in trinity name.

g) House warming in trinity name.

h) Ordination in trinity name.

i) Dedication of institutions of any kind, like, Bible college, schools, shops, halls, vehicles in trinity name.

Many more like this they do in trinity name, which act is against Col. 3:17, which I once again produced below.

Colossians  3:17 And whatsoever ye do in word or deed, do all in the name of the Lord Jesus, giving thanks to God and the Father by him.

Therefore, real Christians, who follow Apostles 7 foundational doctrines, mentioned in Acts. Chapter 2, must avoid these so called nominal Pentecostal groups, who preach and teach against Apostles doctrine. 

Is there any trinitarians can condemn my above statements,  you are welcome and prove where I am wrong.
