Cardinal Raymond Burke gave an interview to a Spanish newspaper and said he did not wish to criticise Pope Francis but added that he felt the faith was being adapted to suit modern culture.
"We are a counter-cultural movement, not a popular one", he told Vida Nueva.
It's not the first time the conservative Cardinal has been critical of the Church. Last month he said he thought the family synod had been manipulated and censored.
In the latest newspaper interview he said: "Now, it is more important than ever to examine our faith, have a healthy spiritual leader and give powerful witness to the faith.
"I fully respect the Petrine ministry and I do not wish it to seem like I am speaking out against the Pope.
"I would like to be a master of the faith, with all my weaknesses, telling a truth that many currently perceive.
"They are feeling a bit sea sick because they feel the Church's ship has lost its bearings. We need to set aside the reason for this disorientation because we have not lost our bearings.
"We have the enduring tradition of the Church, its teachings, the liturgy, its morality. The catechism remains the same."
Despite saying he did not want to criticise the Pope the Cardinal did speak out against Francis' call for Catholics to speak to people about the faith outside of Church.
"The people have responded very warmly to this. But we cannot go to the peripheries empty-handed," he said.
"We go with the Word of God, with the Sacraments, with the virtuous life of the Holy Spirit. I am not saying the Pope does this, but there is a risk of the encounter with culture being misinterpreted.
"Faith cannot adapt to culture but , must call to it to convert. We are a counter-cultural movement, not a popular one."
