The title "Eternal Father" given to Jesus in Isaiah 9:6 doesn't contradict the Trinity but reveals His role as the founder and eternal ruler of God's kingdom. Just as ancient kings were called "fathers" to their people as protectors and providers, Jesus serves as the eternal King whose government rests entirely on His shoulders. While everyone is under His universal rule, citizenship in His kingdom comes only through faith in Christ. As citizens of God's kingdom, we're not just saved from sin but saved to something greater - eternal citizenship under the perfect rule of Jesus Christ, who remains faithful yesterday, today, and forever.
