It says "they worship me in vain." --- who are "they"? In Biblical context, it's the Scribes and the Pharisees, who were teaching the observation of the 613 Mitzvot. This has nothing to do with development of doctrine in Christ's Church under the guidance of the Holy Spirit.

There is no legitimate development of doctrine outside of the scriptures...

Mar_12:38 And he said unto them in his doctrine, Beware of the scribes, which love to go in long clothing, and love salutations in the marketplaces,

Your religion changed that doctrine, didn't it???

Rom_6:17 But God be thanked, that ye were the servants of sin, but ye have obeyed from the heart that form of doctrine which was delivered you.

Rom_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.

1Ti_1:3 As I besought thee to abide still at Ephesus, when I went into Macedonia, that thou mightest charge some that they teach no other doctrine,

Jud 1:3 Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints.

The bible has all the doctrine there ever will be...

That's not so--- it's not Biblical. It negates the work of the Holy Spirit in the Church --- because Our Lord the Holy Spirit leads us into "all truth," not just things past, but things to come.

The development of doctrine cannot be something that negates or contradicts Scripture, since the Holy Spirit is both the Author of Scripture and the Author of the development of doctrine in the Church:

John 16:13
But when he, the Spirit of truth, comes, he will guide you into all the truth. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come.
