Why Do Catholics Do That ?

What is Anointing of the Sick ?
The Sacrament, "Anointing of the Sick," strengthens those suffering a serious illness or infirmity of age.  Anointing can be received more than once in a lifetime.  "Is anyone among you sick?  He should summon the presbyters of the church, and they should pray over him and anoint [him] with oil in the name of the Lord" (James 5:14).
This sacrament also has the effect of uniting the sick to the passion of Christ, giving peace and strength, and forgiving sins.

Why do Catholics gesture before the Gospel reading?
God created us to know him, to love him, and to serve him.  In Mass, when we make the three Signs of the Cross on our foreheads, lips, and hearts before the Gospel reading, we are dedicating ourselves to God.  We pray, "Lord, be on my mind, be on my lips, be in my heart."  We ask God to be in us as we hear the Gospel, so that we can truly" love and serve the Lord" by our lives.

Why do Catholics only get baptized once?
The Catholic Church tells us that Baptism is the gateway to the Church, and the beginning of a lasting communion with God.  At our Baptism, God adopted us as his children and "marked" us as his forever.  This spiritual mark of Christ opens us to grace, helps us resist the temptation to sin, and inspires us to love God and neighbor more perfectly (Catechism of the Catholic Church, #1121).  This mark is permanent, so we are only baptized once.

Why do Catholics call the Church the "Body of Christ"?
On the first Pentecost, the Holy Spirit descended on the Apostles and united them as one Body to continue Christ's saving work.  "For by one Spirit we were all baptized into one body-Jews or Greeks, slaves or free-and all were made to drink of one Spirit"  (Corinthians 12:13).  The Church is made up of all God's people, united by Baptism, each with a unique role.  We act as Christ's Body on Earth, with Christ as our head.

Why do Catholics pray the Rosary?
The Rosary is a simple prayer adapted from the complex set of prayers of medieval monks.  It's a powerful prayer because in it, we ask Mary ---- whose prayers are never refused ---- to pray for us.  In addition, through the mysteries of the Rosary, we meditate on the life of Jesus which always bears fruit.  For example, the fruit of the mystery of the Annunciation is humility.  Praying the Rosary opens us to graces that help us be more Christ-like.
