Why do Catholics believe that God is three Persons, called the Holy Trinity? How can God be three Persons and still be one God?
 

Catholics believe there is one God consisting of three distinct and equal divine Persons--Father, Son and Holy Spirit--because on numerous occasions God has described Himself thus. The Old Testament gives intimations that there are more than one Person in God. In Genesis 1:26, God says, ``Let us make man to our image and likeness.'' In Isaias 9:6-7, God the Father revealed the imminent coming into the world of God the Son. In Psalms 2:7, we read, ``The Lord hath said to me: Thou art my son, this day have I begotten thee.'' And in the New Testament, God reveals this doctrine even more clearly. For example, at the baptism of Jesus Christ, the Holy Spirit appeared in the form of a dove, and the voice of God the Father was heard: ``This is my beloved Son, in whom I am well pleased.'' (Matt. 3:16-17). In Matthew 28:19, God the Son commanded the Apostles to baptize ``in the name of the Father, and of the Son, and of the Holy Ghost.'' And in 1 Cor. 12:4-6, the Bible refers to God with three names: Spirit, Lord, and God-- corresponding to the Father, the Son, and the Holy Spirit.

Three divine Persons in one Godhead may be incomprehensible to the human mind, but that is to be expected. How can man fully comprehend God's infinite make-up when he cannot fully comprehend his own finite make-up? We have to take God's word for it. Also, we can satisfy ourselves as to the feasibility of God's triune make-up by considering various other triune realities. The triangle, for example, is one distinct form with three distinct and equal sides. And the clover leaf is one leaf with three distinct and equal petals. There are many physical trinities on earth, therefore a Spiritual Trinity, who is God in Heaven, is not against human reason--it is simply above human reason.
 

Why do Catholics believe that Jesus Christ was God the Son--the Second Person of the Holy Trinity? Would it not be more reasonable to believe that He was a great and holy man... a religious leader of exceptional talent and dedication... a prophet?
 

Catholics believe that Jesus was God the Son, incarnate in human flesh, firstly because God's physical manifestation on earth, plus all the circumstances of that manifestation, were prophesied time and again in Divine Revelation, and Jesus fulfilled that prophecy right to the letter; secondly, because He claimed that He was God (John 10:30, 14:9-10 and numerous other passages), and He never deceived anyone; thirdly, because He proved His divinity by His impeccable holiness and the flawless perfection of His doctrine; fourthly, because only God could have performed the miracles He performed miracles such as walking on the sea, feeding five thousand people with five loaves of bread and two fish, and, after His death on the Cross, resurrecting Himself from His own tomb; fifthly, because only God could have, in the brief space of three years, without military conquest, without political power, without writing a single line or traveling more than a few score miles, so profoundly affected the course of human events; sixthly, because only God can instill in the soul of man the grace and the peace and the assurance of eternal salvation that Jesus instills.
 

Why do Catholics believe that their Church is the one true Church of Jesus Christ? Wouldn't it be more reasonable to believe that Christ's true Church is a spiritual union of all Christian denominations?
 

Catholics believe that theirs is the one true Church of Jesus Christ, firstly, because theirs is the only Christian Church that goes back in history to the time of Christ; secondly, because theirs is the only Christian Church which possesses the invincible unity, the intrinsic holiness, the continual universality and the indisputable apostolicity which Christ said would distinguish His true Church; and thirdly, because the Apostles and primitive Church Fathers, who certainly were members of Christ's true Church, all professed membership in this same Catholic Church (See Apostles' Creed and the Primitive Christian letters). Wrote Ignatius of Antioch, illustrious Church Father of the first century: ``Where the Bishop is, there let the multitude of believers be; even as where Jesus is, there is the Catholic Church.'' Our Lord said: ``There shall be one fold and one shepherd, yet it is well known that the various Christian denominations cannot agree on what Christ actually taught. Since Christ roundly condemned interdenominationalism (``And if a house be divided against itself, that house cannot stand.'' Mark 3:25), Catholics cannot believe that He would ever sanction it in His Church.
 

Why do Catholics believe in seven sacraments, while Protestants believe in only two? Exactly what is a sacrament, and what does it do for a person?
 

Catholics believe in seven sacraments because Christ instituted seven; because the Apostles and Church Fathers believed in seven; because the second Ecumenical Council of Lyons (1274) defined seven; and because the Ecumenical Council of Trent (1545-1563) confirmed seven. In short, the enumeration, seven, arises from the perpetual tradition of Christian belief--which explains why that enumeration is accepted not only by Catholics, but by all of the other ancient and semi-ancient Christian communities--Egyptian Coptic, Ethiopian Monophysite, Syrian Jacobite, Greek Orthodox and Russian Orthodox.

To understand what a sacrament is, and what it does for a person, one must know the correct, the traditional Christian, definition of a sacrament. Properly defined, a sacrament is ``an outward sign instituted by Christ to give grace'' (holiness) to the soul . . . that is to say, it is a divinely prescribed ceremony of the Church in which the words and action combine to form what is at the same time both a sign of divine grace and a fount of divine grace. When this special grace--distinct from ordinary, inspirational grace--is imparted to the soul, the Holy Spirit of God is imparted to the soul, imbuing the soul with divine life, uniting the soul to Christ.

As the Scriptures point out, this grace is the grace of salvation--without it man is, in a very real sense, isolated from Christ. And as the Scriptures point out, Christ gave His Church seven sacraments to serve as well-springs of this ineffable, soul-saving grace, the grace which flows from His sacrifice on Calvary:

BAPTISM--the sacrament of spiritual rebirth through which we are made children of God and heirs of Heaven: ``Amen, amen I say to thee, unless a man be born again of water and the Holy Ghost, he cannot enter into the kingdom of God.'' (John 3:5. Also see Acts 2:38, Rom. 6:2-6).

CONFIRMATION--the sacrament which confers the Holy Spirit to make us strong and perfect Christians and soldiers of Jesus Christ: ``Now when the apostles, who were in Jerusalem, had heard that Samaria had received the word of God, they sent unto them Peter and John. Who, when they were come, prayed for them, that they might receive the Holy Ghost.... Then they laid their hands upon them, and they received the Holy Ghost.'' (Acts 8:14-17. Also see Acts 19:6).

The EUCHARIST--the sacrament, also known as Holy Communion, which nourishes the soul with the true Flesh and Blood, Soul and Divinity of Jesus, under the appearance, or sacramental veil, of bread and wine: ``And whilst they were eating, Jesus took bread; and blessing, broke, and gave to them, and said: Take ye. This is my body. And having taken the chalice, giving thanks, he gave it to them. And they all drank of it. And he said to them: This is my blood of the new testament, which shall be shed for many.'' (Mark 14:22-24. Also see Matt. 26:26-28, Luke 22:19-20, John 6:52-54, 1 Cor. 10:16).

RECONCILIATION--the sacrament, also known as Confession, through which Christ forgives sin and restores the soul to grace: ``Receive ye the Holy Ghost. Whose sins you shall forgive, they are forgiven them; and whose sins you shall retain, they are retained. '' (John 20:22-23. Also see Matt. 18:18).

SACRAMENT OF THE SICK--this sacrament strengthens the sick and sanctifies the dying: ``Is any man sick among you? Let him bring in the priests of the church, and let them pray over him, anointing him with oil in the name of the Lord . . . and if he be in ,ins, they shall be forgiven him.'' (James 5:14-15. Also see Mark 6:12-13).

HOLY ORDERS--the sacrament of ordination which empowers priests to offer the Holy Sacrifice of the Mass, administer the sacraments, and officiate over all the other proper affairs of the Church: ``For every high priest taken from among men, is ordained for men in the things that appertain to God, that he may offer up gifts and sacrifices for sins.... Neither doth any man take the honor to himself, but he that is called by God, as Aaron was.'' (Heb. 5:1-4. Also see Acts 20:28, 1 Tim. 4:14). Also: ``And taking bread, he gave thanks, and broke; and gave to them, saying: This is my body, which is given for you. Do this for a commemoration of me.'' (Luke 22:19).

MATRIMONY--the sacrament which unites a man and woman in a holy and indissoluble bond: ``For this cause shall a man leave father and mother, and shall cleave to his wife, and they two shall be in one flesh. Therefore now they are not two, but one flesh. What therefore God hath joined together, let no man put asunder.'' (Matt. 19:5-6. Also see Mark 10:7-9, Eph. 5:22-32).

There you have it, the Word of Christ and the example of the Apostles attesting both to the validity and the efficacy of the seven Sacraments of the Catholic Church. In truth, every one of them is an integral part of Christ's plan for man's eternal salvation.
