Yes. Through the centuries many elaborate ceremonies have been developed. This is understandable. Ceremony and ritual are valuable psychological tools for making lasting impressions. Since the time of confirmation is an event to remember, it is a fitting occasion for ceremony and ritual. However, the New Testament records very simply that the apostles went around confirming their converts after their initial experiences with Christ in repentance, faith, water baptism, and receiving the Holy Spirit.

Confirmation followed a time of being taught.

And when they had preached the gospel to that city, and had taught many, they returned to Lystra, and to Iconium, and Antioch, confirming the souls of the disciples, and exhorting them to continue in the faith, and that we must through much tribulation enter into the kingdom of God (Acts 14:21, 22).

They had taught in the cities previously. They allowed the disciples time to solidify their own decisions to believe and to commit themselves to Christ. Then they went back and confirmed them, probably laying hands upon them and praying, as well as warning them that tribulation or trouble is normal for the Christian life. We cannot avoid it, but we can be inwardly fortified to face it and master it.

Confirmation includes exhortations to continue as we have begun.

And Judas and Silas, being prophets also themselves, exhorted the brethren with many words, and confirmed them (Acts 15:32).

Laying on of hands is not enough. We must be stirred and challenged through words of warning and hope. The discipline we mastered in order to become disciples or learners, will be required throughout our lifetime to enable us to live as examples of Christ in a world full of darkness.

Confirmation means the giving of real inner strength.

And after he [Paul] had spent some time there [in Antioch], he departed, and went over all the country of Galatia and Phrygia in order, strengthening all the disciples (Acts 18:23).

Sometimes the whole church was confirmed.

And Paul chose Silas, and departed, being recommended by the brethren unto the grace of God. And he went through Syria and Cilicia, confirming the churches (Acts 15:40, 41).

Without the confirmation through apostles and evangelists, a local church could suffer isolation from the larger Body of Christ. It is important to know that we belong to one another when we are a part of Christ. This belonging is much bigger than even our local community. The local church can act with confidence when its leaders are assured that they are acting along with others all over the world. We all want to be sure we are a part of what God is doing in the Earth today.
