The Catholic Church rarely pronounces infallible dogmas or teachings concerning the interpretation of Scripture. Usually, this is not done unless the correct interpretation is needed in order to understand the Church’s teachings.
An example is John 6:55 “For My flesh is food indeed, and My blood is drink indeed.”
The Catholic Church teaches that this Scripture is literal. We actually eat the Body and Blood of Christ in Holy Communion/Holy Eucharist. Paschal lambs must be literally eaten.
Another one is the Filioque which is one of the reasons for the continuation of the East/West Schism. (Another is papal infallibility.) This Catholic Filioque teaching can be proved by the correct interpretation of Scripture.
The Filioque is the teaching of the Catholic Church that the Holy Spirit proceeds from the Father and the Son. The Orthodox Church teaches that the Holy Spirit proceeds from the Father.
How do the Three Persons of God work together as One?
Jesus states in John 14:16-18 “I will ask the Father, and He will give you another Helper, that He may be with you forever; 17that is the Spirit of truth, whom the world cannot receive, because it does not see Him or know Him, but you know Him because He abides with you and will be in you. 18"I will not leave you as orphans; I will come to you.”
First, Jesus asks His Father to give the Holy Spirit as Helper to the Church on earth.
John 14:26 “But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all that I said to you.”
Then, the Father Wills (gives) what Jesus asks and wills the Helper to be sent in Jesus’ name to the Church on earth."
**
The Holy Spirit proceeds from the Father first.**
John 15:26 “But when the Helper comes, whom I shall send to you from the Father, the Spirit of truth who proceeds from the Father, He will testify of Me.”
John 16:7-15 “But I tell you the truth, it is to your advantage that I go away; for if I do not go away, the Helper will not come to you; but if I go, I will send Him to you. 8"And He, when He comes, will convict the world concerning sin and righteousness and judgment; 9concerning sin, because they do not believe in Me; 10and concerning righteousness, because I go to the Father and you no longer see Me; 11and concerning judgment, because the ruler of this world has been judged. 12"I have many more things to say to you, but you cannot bear them now. 13"But when He, the Spirit of truth, comes, He will guide you into all the truth; for He will not speak on His own initiative, but whatever He hears, He will speak; and He will disclose to you what is to come. 14"He will glorify Me, for He will take of Mine and will disclose it to you. 15"All things that the Father has are Mine; therefore I said that He takes of Mine and will disclose it to you.”
**
First the Holy Spirit proceeds from the Father and then the Holy Spirit proceeds from the Son.**
Jesus’ Word (verbally) sends the Holy Spirit (Power) to do the Will of the Father.
(The Father’s Will is to send the Holy Spirit in Jesus’ name as Helper to Jesus’ Church on earth.)
The Holy Spirit then fulfills the will of the Father when He is sent by the Son to the Church on earth. So the Holy Spirit proceeds from the Father and the Son.
The Catholic Church is correct. The Filioque is Truth, so the Orthodox Church is incorrect. The Orthodox Church teaches mostly Truth, but they do not teach all Truth.
This is why there is only one “keeper of the keys of heaven.” Jesus promised His one Church, the one with the “keeper of the keys of heaven,” (the one with the Pope) that He would guide His one Church to teach all His truth on earth until He returns. [John 16:13] His Church’s teachings are infallible/without error. The Holy Spirit prevents His one Church from teaching error. His Church is One, Holy, Catholic/universal, and Apostolic.
He started only One Church.
It is Holy because the Holy Spirit guides it into all truth.
It is Catholic which means universal. His Church is everywhere on earth.
It is Apostolic. It’s hierarchy remains unbroken in lineage since the first Apostles. The hierarachy continued His Church by the laying on of hands for Holy Orders (bishop, priest, and deacon) and this is called Apostolic Succession. [2 Timothy 2:2, 1 Timothy 4:14]
