Heresy regarding the Christian walk.

This was on a church's website.

"The freedom we have in Christ sets us free from the restrictions of legalistic rituals and religious regulations.

"My Prayer

Heavenly Father, thank You for the freedom I have in Christ. Thank You that I am not under any form of the Law, but under grace. Keep me from sin, I pray,"

Many churches teach Christians are not required to do rituals and obey regulations, because they are under grace.

A ritual is

"an act or series of acts regularly repeated in a set precise manner"

Merriam-Webster dictionary.

What about Baptism and the Lord's Supper?

Regulations are

"the state of being [brought] under the control of law or constituted authority"

Merriam-Webster dictionary.

Are not Christians to be under God's authority?
