Combining Christian marriage rite and other religious marriage rite

In my little understanding, being part of any religion is a choice, if you become a Christian then Christianity becomes your *lifestyle/tradition/regulations*

thus

"If we [claim to] live by the [Holy] Spirit, we must also walk by the Spirit [with personal integrity, godly character, and moral courage—our conduct empowered by the Holy Spirit]." (Galatians 5:25 amp).

This is how Jesus presented it

"Now large crowds were going along with Jesus; and He turned and said to them, 26 “If anyone comes to Me, and does not hate his own father and mother and wife and children and brothers and sisters, yes, and even his own life [in the sense of indifference to or relative disregard for them in comparison with his attitude toward God]—he cannot be My disciple. 27 Whoever does not carry his own cross [expressing a willingness to endure whatever may come] and follow after Me [believing in Me, conforming to My example in living and, if need be, suffering or perhaps dying because of faith in Me] cannot be My disciple. 28 For which one of you, when he wants to build a watchtower [for his guards], does not first sit down and calculate the cost, to see if he has enough to finish it? 29 Otherwise, when he has laid a foundation and is unable to finish [the building], all who see it will begin to ridicule him, 30 saying, ‘This man began to build and was not able to finish!’ 31 Or what king, when he sets out to meet another king in battle, will not first sit down and consider whether he is strong enough with ten thousand men to encounter the one who is coming against him with twenty thousand? 32 Or else [if he feels he is not powerful enough], while the other [king] is still a far distance away, he sends an envoy and asks for terms of peace. 33 So then, none of you can be My disciple who does not [carefully consider the cost and then for My sake] [b]give up all his own possessions." (Luke 14:25-33 amp).

The Gospel of Jesus Christ Crucified is *a proposal of a new tradition/lifestyle/regulation to each human being by God's grace ("But we do see Jesus, who was made lower than the angels for a little while [by taking on the limitations of humanity], crowned with glory and honor because of His suffering of death, so that by the grace of God [extended to sinners] He might experience death for [the sins of] everyone." Hebrews 2:9)

and if anybody is willing to collaborate with the Holy Spirit and accept this new lifestyle/tradition(Christianity) then we should allow them to hold-unto what they believe unless you have a stronger-point to present your own religion as better than theirs and they weigh it and choose to follow your new proposition *willingly* then you can have them obey your rules.
