Trinity Lutheran Church welcomes members into our community of faith in many ways.

  • Being baptized at Trinity automatically makes one a baptized member of Trinity.
  • Adult members and families may transfer their membership to Trinity from other Lutheran Church-Missouri Synod congregations.
  • Other Christians may join Trinity after completing our Membership Exploration Class,which teaches about Trinity and reviews the basics of the Christian faith.
  • Those becoming Christians also complete the Membership Exploration Class, at which time they may be baptized and confirmed in the Christian faith. Call 630.894.3263 for more information.
If you are interested in learning more about membership, connecting with people of Trinity and engaging in some of our ministries, maybe it’s time to come to our next “Start Here” open house held on the last Sunday of the month. Stop in before or after services in the Resurrection Chapel, just off the Lobby.
If you want to hear about our Membership Exploration Class (offered 3-4 times a year) or have questions about our “Start Here” open house, please contact Amy Herring at amyh@trinityroselle.com. Or call our church office directly at 630.894.3263
Trinity Lutheran Church is happy to arrange for the baptism of children and adults. Baptisms normally occur during worship services. Those interested in having their children baptized attend a 1.5 hour pre-baptism course offered on the third Thursday of each month. Babysitting is provided. Teenagers and adults normally complete confirmation instruction prior to being baptized. Call 630.894.3263 to begin the process
Please complete this form to submit your prayer request.
The privilege of being married at Trinity is reserved for those who publicly practice their Christian faith. That is most clearly seen in regular worship attendance. Typically, weddings are limited to Friday evenings, Saturdays afternoons, and Sundays after 1 p.m. Those interested in having their wedding at Trinity must first meet with one of the pastors prior to setting the date. At that time, details regarding the wedding will be discussed. Other requirements include participation in four pre-marital counseling sessions. Call 630.894.3263 to inquire about the availability of wedding dates and to arrange for a meeting with a pastor. Complete info here.
One does not have to be a member of Trinity for a pastor to perform a funeral service for someone. Members may choose to have a funeral in the Sanctuary, funeral home, or cemetery. Non-member funerals are typically limited to the funeral home or cemetery and may be arranged if there is an available pastor. Call 630.894.3263 for more information.
At Trinity, children going into seventh grade begin confirmation class. Spread over two years, these classes teach the basics of the Christian faith from Luther’s Small Catechism. These include the Ten Commandments, the Apostles’ Creed, the Lord’s Prayer, the Sacraments of Baptism and the Lord’s Supper, and the “Office of the Keys,” or forgiveness. In addition, students grow in their faith relationship with God and their relationships with others. After being instructed in the Lord’s Supper, students may choose to receive this Sacrament prior to their confirmation. The confirmation experience ends with the Rite of Confirmation, held in the Fall. At that time, students become communicant members of Trinity Lutheran Church. Call 630.894.3263 for more information.
The pastoral staff of Trinity Lutheran Church works as a team ministry. You will always be able to contact one of them, day or night. We have voice mail, pagers, and listed phone numbers. Senior Pastor Charles Mueller Jr., Pastor Randy Rozelle and Pastor Doug Warmann will be happy to hear from you in person, by phone (630.894.3263). You can also connect via our Contact Us page.

As someone considering the Christian faith, you must deal with two important questions:

Do you know for certain that you have eternal life and will go to heaven if you were to die today?
If you died and stood before God and He were to ask you, “Why should I let you into heaven?” what would you say?

How you answer those two questions is not inconsequential. They show where you are spiritually within the Christian faith. Are there wrong answers? You bet! Lots of them. Two answers bring the Christian faith into focus. To the first question, Christians will answer “Yes, for sure, absolutely.” Many people will say that. But a second answer is required. Christians respond to the second question with these words: “Because Jesus died for my sins.” If those two are not your answers, perhaps you need to consider the following “ABC’s” of the Christian faith.


A: Admit your failure to follow God and His will perfectly. For all have sinned and fall short of the glory of God. – Romans 3:23

Whoever keeps the whole law and yet stumbles at just one point is guilty of breaking all of it. – James 2:10
Cursed is everyone who does not continue to do everything written in the Book of the Law. – Galatians 3:10
For the wages of sin is death. – Romans 6:23

B: Believe what God has done for you in Jesus Christ.For God so loved the world that He gave His one and only Son, that whoever believes in Him shall not perish but have eternal life. – John 3:16
Christ Jesus came into the world to save sinners. – 1 Timothy 1:15
For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures, that He was buried, that He was raised on the third day. – 1 Corinthians 15:3-4
Christ redeemed us from the curse of the law by becoming a curse for us. ` – Galatians 3:13
For Christ died for sins once for all, the righteous for the unrighteous, to bring you to God. – 1 Peter 3:18
He saved us, not because of righteous things we have done, but because of His mercy. – Titus 3:5
The gift of God is eternal life in Christ Jesus our Lord. – Romans 6:23
Believe in the Lord Jesus, and you will be saved. – Acts 16:31Do you believe that Jesus Christ lived a perfect life, died on the cross, and rose from the dead for you?A prayer for this moment might be:
Lord Jesus Christ, I confess that I am a sinner and do not deserve eternal life. But You died on the cross and rose from the dead to purchase a place in heaven for me. Thank You for giving me faith by the power of Your Holy Spirit, forgiveness of all my sins, and the gift of eternal life. Help me to live for You and to confess You before others. In Your name I pray. Amen.
C: Confess your faith to others in response to God’s goodness.Whoever confesses me before men, I will also confess before My Father who is in heaven. – Matthew 10:32
If you confess with your mouth, “Jesus is Lord,” and believe in your heart that God raised Him from the dead, you will be saved. – Romans 10:9So now you have begun. These are the ABCs of becoming a Christian. There is much more to learn and understand about your Lord, your faith, and His Church. If you have any questions, call us at 630.894.3263 and we will be happy to respond to your questions and needs.We encourage you to attend the Membership Exploration Class to gain a full understanding of the Christian Faith.
